Azure Pipelines could not run because the pipeline triggers exclude this branch/path.

can you merge this @elinor-fung as you see fit? I don't think test only needs approval.

@carlossanlop / @jeffschwMSFT - what is the policy/openness of the release/6.0 branch for the test changes here?

Context: the Server 2019 helix queue we are using is being removed 31-MAR and we need to (backport the) switch to the Server 2022 queue. These test-only changes are needed for the tests to run cleanly on Server 2022. The separate infrastructure-only change to switch to 2022 - #67054 - hit the test failures.

Thanks for elevating this. I agree this is tell mode and we just need to ensure that the branch is open for a checkin. Carlos should be able to let us konw.
