Improvements on conformance page

[jedel1043]

Our current conformance page is very simple in functionality, so it would be great to add a bit more improvements on the UX side to make it a bit more usable overall.

List of possible improvements

• Search bar for tests/suites/both.
• Instantly show the test name when hovering on the outcome square. (Add aria-label and grid header on test hover #152)
• Add a checkbox to hide all passed tests.
• Enable using the Go back and Go forward buttons to return to the last visited tag/suite/test. (Refactor Conformance page to allow back and forward history #150)
• Show the tests as a list of test names.
• Hide empty suites when the ES version selector changes. (Filter out empty suite results for version #153)
• Sort tests alphabetically. (Build out sorting functionality feature to conformance page #151)

I'd really like the test results to be alphabetically sorted (not hard, just haven't gotten around to it).

Another idea I think it'd be interesting to explore is an "Open in Playground" option that will load the test into the Boa playground, which would be really cool combined with boa-dev/boa#3227

Why stop there? We could also allow sorting by ES version, by outcome result, inverse alphabetical, etc.

We can definitely expand on that. Mostly wanted it as the default 😆
