package-and-qa job does not auto run based on MR labels as intended

Summary

In !89511 (merged), we introduced the ability to auto-run package-and-qa if the QA_TESTS variable is set. We would only run the jobs that would run the files specified by QA_TESTS.

But this is not working as expected. For example, here is a pipeline for this MR that should have auto-run package-and-qa job as the QA_TESTS variable was set
