build: several minor fixes related to using puppeteer

This is a follow-up to #35049 with a few minor fixes related to using the browser provided by puppeteer to run tests. Included fixes:

Make the webdriver-manager-update.js really portable. (Previously,
it needed to be run from the directory that contained the
node_modules/ directory. Now, it can be executed from a subdirectory
and will correctly resolve dependencies.)
Use the puppeteer-based setup in AIO unit and e2e tests to ensure
that the downloaded ChromeDriver version matches the browser version
used in tests.
Use the puppeteer-based setup in the aio_monitoring_stable CI job
(as happens with aio_monitoring_next).
Use the recommended way of getting the browser port when using
puppeteer with lighthouse and avoid hard-coding the remote
debugging port (to be able to handle multiple instances running
concurrently).

build(docs-infra): use puppeteer to get a browser for docs examples tests

In #35049, integration and AIO tests were changed to use the browser provided by puppeteer in tests. This commit switches the docs examples tests to use the same setup.

IMPLEMENTATION NOTE:
The examples are used to create ZIP archives that docs users can download to experiment with. Since we want the downloaded projects to resemble an @angular/cli generated project, we do not want to affect the project's Protractor configuration in order to use puppeteer.

To achieve this, a second Protractor configuration is created (which is ignored when creating the ZIP archives) that extends the original one and passes the approperiate arguments to use the browser provided by puppeteer. This new configuration (protractor-puppeteer.conf.js) is used when running the docs examples tests (on CI or locally during development).

ci: get rid of the CI_CHROMEDRIVER_VERSION_ARG env var

Previously, we needed to manually specify a ChromeDriver version to download on CI that would be compatible with the browser version provided by the docker image used to run the tests. This was kept in the CI_CHROMEDRIVER_VERSION_ARG environment variable.

With recent commits, we use the browser provided by puppeteer and can determine the correct ChromeDriver version programmatically. Therefore, we no longer need the CI_CHROMEDRIVER_VERSION_ARG environment variable.

NOTE:
There is still one place (the bazel-schematics integration project) where a hard-coded ChromeDriver version is necessary. Since I am not sure what is the best way to refactor the tests to not rely on a hard-coded version, I left it as a TODO for a follow-up PR.

This is a follow-up to angular#35049 with a few minor fixes related to using the browser provided by `puppeteer` to run tests. Included fixes: - Make the `webdriver-manager-update.js` really portable. (Previously, it needed to be run from the directory that contained the `node_modules/` directory. Now, it can be executed from a subdirectory and will correctly resolve dependencies.) - Use the `puppeteer`-based setup in AIO unit and e2e tests to ensure that the downloaded ChromeDriver version matches the browser version used in tests. - Use the `puppeteer`-based setup in the `aio_monitoring_stable` CI job (as happens with `aio_monitoring_next`). - Use the [recommended way][1] of getting the browser port when using `puppeteer` with `lighthouse` and avoid hard-coding the remote debugging port (to be able to handle multiple instances running concurrently).

I think we still need this for one last test which is the integration/bazel-schematics. Once that is updated to puppeteer we can finally kill it.

Ahh. I see you hard-coded it there instead 👍 👍

For local testing I suppose you're no relying on the browser popping up and if you need it you can always change this temporarily?

Yeah, exactly. I still needed to pass some flags for the puppeteer-provided Chrome to work locally (at least on Windows) and I realized we hardly ever need the browser. For debugging you can always open a browser and point it to the Karma URL (or change this config temporarily as you mentioned).

😎

I was avoiding yarn as in a follow up PR i'll run the aio build in npm_integration_test so under Bazel I want to ensure that the correct version of yarn is used. However, under Bazel I think yarn will be on the path and it will redirect to the Bazel provisioned yarn to be hermetic.

However, this may now be more an issue outside of Bazel now since we're relying on the root .yarnrc to use yarn 1.21.1 and in this context there will be no .yarnrc in the cwd. + @josephperrott 👀

I think this will end up using the locally installed yarn now which may be out of date

Yarn is clever enough to look at parent directories and find the closest .yarnrc (if any). So, it will use our vendored version regardless of the directory.

If this turns out to be a problem for bazel, we can use require.resolve() to find the relative path to the closest node_modules/ directory (but yarn was easier for now and from what I understand it might work in bazel too).

That's true for .yarnrc as I had to sift through that code to get yarn_install to honor .yarnrc and the yarn-path. However, there is special treatment for the yarn-path setting as it is a start-up setting; it may only be used if it is in a .yarnrc in the cwd as otherwise you can get into infinite recursion situations. You may be right however but should verify that is the case.

Confirmed that it picks up the version from .yarnrc as desired.

👍 Thanks @josephperrott

LGTM. Will be some conflict with #33927 but this will probably land first tho so I'll handle the conflicts on rebase.

After #33927 and this land I should be able to run aio in an npm_integration_test :)

LGTM

… ZIP archives In angular#35381, a new Protractor config file was introduced in docs examples, `protractor-puppeteer.conf.js`, that was only supposed to be used on CI and not be shipped with the ZIP archives provided for users to download and experiment with the docs examples locally. The logic to ignore the `protractor-puppeteer.conf.js` file was incorrect, resulting in the file being retained in some examples (e.g. [universal][1]). The problem was not immediately obvious, because most examples explicitly specify all `**/*.js` files as ignored, but for other examples the file was retained in the ZIP archive. This commit fixes the logic to ensure the file is excluded from all docs examples ZIP archives. [1]: https://v9.angular.io/generated/zips/universal/universal.zip
