James Graham a91e68a38c Bug 1685532 [wpt PR 27075] - Lint cases where reftest-wait.js is used but class=reftest-wait isn't, a=testonly
Automatic update from web-platform-tests
Fix reftest-wait usage in some tests

--
Add a lint that anything that uses the reftest-wait script specifies reftest-wait

Not having the reftest-wait class on the root is a pretty clear indication of a bug
and one that's relatively easy to avoid. Of course this doesn't catch all cases where
something happens after load and reftest-wait is required but it at least catches some
of the more obvious errors

--
Fix mypy annotations for parsing

--
Update tools/lint/rules.py
