After Philip's CL today which updated web-platform-tests documentation, I
realized I didn't have a quick way to manually check all of the links, but there
are Chrome extensions which do link checking, so I quickly checked some links in
related documentation.

Main changes:

 - WPTServeExpectations doesn't exist anymore.
 - Can't find skia_test_expectations.txt, I guess that also doesn't exist
anymore?
 - Other minor corrections.

I also use https://validator.w3.org/checklink some times to find broken links,
but it probably wouldn't have been useful here.
