    # This job works around an issue with actions/checkout @v2 and @v3 where if
    # a workflow is triggered by an annotated tag push, the tag may not be
    # visible to git in the cloned repository. The issue for that problem is at
    # https://github.com/actions/checkout/issues/290
    # The workaround implemented here does two things:
    # 1. After checking out the repo, there is a step in this job that force
    #    fetches tags. This ensures that all tags are available locally.
    # 2. Image names are determined and saved. These image names are derived
    #    from the certain files and tags in the repo. Dependant jobs use the
    #    images names stored in this job.
    # Image names must be cached after force fetching tags in a single job
    # instead of force fetching tags in each job because if a new release tag is
    # pushed while a workflow is running it's possible the derived image names
    # could change from job to job, breaking the running workflow in a difficult
    # to understand way.
