Ensure Test coverage in PR builds is complete #7439
Description
For the past couple of weeks we've been moving some of our test execution from Helix to also run on GitHub Actions to help running them more efficiently, but at the time, we had not disabled them from also running in Helix as we were mostly doing it as a proof of concept. Today, an intermittent outage with one of our container registries pushed us to need to fully disable tests running in Helix in order to be able to unblock progress and being able to merge changes in.
This issue is meant to track the investigation of all of the tests that still need to be moved into GHA and were only running in Helix, which after the change above we are no longer covering in PRs. Once we have the list of missing things, we should then use this issue to also track the progress of moving all of those to github actions.
This should be done for 9.1.
