  # Stage tests have passed or skipped
  # so it is safe to update the stage branch with the changes in dev, promote the version to an RC, and rebuild and upload the RC to JFrog
  # We store the subsequent jobs after the stage tests in a separate reusable workflow...
  # because if stage tests were skipped, all subsequent jobs will be skipped by default too (both direct and indirect descendents)
  # This means we have to add a manual check for each subsequent job that checks if the stage tests were skipped in order to run them
  # It's easier to just add this manual check once to a reusable workflow that wraps around all the subsequent jobs
