Mergeback v4.38.1 refs/heads/releases/v4 into main

Changing `NO_CHANGES_STR` to just be the text will make it easier to insert/use. To not break anything, I added the deleted newlines to the locations where `NO_CHANGES_STR` was used.

This will be used by the `pr-checks/changenotes.mts` script to "compile" the latest release entry of CHANGELOG.md.

This command will "flush" or move the changenotes in the `unreleased-change-notes` directory to the `[UNRELEASED]` section of the CHANGELOG.md file.

…out_path` itself

Add `changenotes.mts assemble` command to move changenotes to CHANGELOG.md

This reduces duplicate code between `assemble` and `validate`. It also has the benefit of fixing a bug in the current implementation of `validate`, where `isValidChangenoteFile` receives a relative file name where it should receive an absolute one.

Refactor how the `checkout_path` input is obtained
