Clean up fixed bugs for passing tests

[foolip]

https://wpt.fyi/results/css/css-transforms?label=experimental&label=master&aligned now shows a bunch of bug icons for tests that are passing:

This is not great when trying to look through failures and their bugs, it's basically adding visual noise.

@KyleJu do you think this could be cleaned up in wpt-metadata, or would it make more sense to fix it in wpt.fyi by not showing the icon for green cells?

Another category of cleanup is bugs that are closed but the failures remain. Those need re-triage.

@KyleJu do you have any thoughts about how this could be implemented?

I keep removing closed bugs manually with PRs like these:

• Unlink crbug.com/803103 (fixed) #3260
• Unlink crbug.com/1175179 (closed umbrella bug) #3806
• Unlink closed crbug.com/1093539 #4077
• Unlink fixed crbug.com/767352 #4122
• Unlink closed Chrome tracking bug for :has() #4779
• Unlink closed Chrome tracking bug for color() #4785
• Unlink closed Chrome tracking bug for trig functions #4791
• Unlink closed Chrome tracking bug #4874
• Unlink closed Chrome bug for at-property.html test #4916
• Unlink fixed https://crbug.com/1220144 #4943

Since I just apply a mechanical rule of "test is passing in stable and experimental and bug is closed" this could be automated.

@past can you consider this for future planning? It would make it easier to keep the triage of Interop 202X failures up-to-date.

Agreed that this would be nice to have, I added it to our backlog.
