Bug description

Hi all, hope you're well. Just a quick note to point out that a potentially-useful article from the wiki appears to have been (unintentionally?) deleted or overwritten.

It appears that you've turned off wiki editing, but here are the steps I would've taken to fix it:

git clone https://github.com/php-webdriver/php-webdriver.wiki.git

# the last revision that had useful content (which is still accurate)
git checkout a576b7f Taking-Full-Screenshot-and-of-an-Element.md

# the title has a grammar mistake, so fix it
git mv Taking-Full-Screenshot-and-of-an-Element.md Taking-a-screenshot.md

git commit -am'Restore "taking a screenshot" article that was corrupted'
git push origin master

How could the issue be reproduced

Visit the "Taking Full Screenshot and of an Element" article and note that the page is basically empty.

Other details

Revision a576b7f from the wiki repository points to https://github.com/php-webdriver/php-webdriver/wiki/Example-command-reference#screenshots, which is the current and correct reference.

In my opinion, though, it's still very helpful to have "Taking a screenshot" or some similar article title appearing in the wiki's sidebar.
