[CI] Fix Outerloop workflow, and run the workflows every four hours (#13304)

* Fix Outerloop workflow, and run Quarantine tests every four hours

* Fix run_tests job to run when build_packages is skipped

- Add !cancelled() && !failure() condition to run_tests job so it
  proceeds when build_packages is skipped (requiresNugets is false)
- Update results job failure check to not fail when build_packages
  is skipped, since that's expected behavior
