announcing failure data in searchfox

[Joel Maher]

searchfox does a lot of great things.  A couple of years ago we removed some functionality to integrate test failure data into the related information when viewing a test case, since then we have only have `skip-if` type data from a test manifest:

https://searchfox.org/mozilla-central/source/netwerk/test/unit/test_http3.js

Recently we updated the `test-info` jobs that run on mozilla-central ( https://treeherder.mozilla.org/jobs?repo=mozilla-central&searchStr=test-info-all ).  These produce artifacts that include historical failure data mapped to each test (see https://bugzilla.mozilla.org/show_bug.cgi?id=1777063 ).  That data is ingested into searchfox ( https://bugzilla.mozilla.org/show_bug.cgi?id=1777009 - thanks :asuth), providing more useful data when viewing a test case:

The CI Automation and Tools team is planning on more work in H2 to improve visibility and accuracy of test run data.

Feel free to reach out to myself (:jmaher) or chat on Matrix (#firefox-ci) about test data that you wish you had, or integration points (like searchfox, bugzilla, treeherder, etc.) that you would like to see.
