    # Force fetch upstream tags -- because 65 minutes
    # tl;dr: actions/checkout@v2 runs this line:
    #   git -c protocol.version=2 fetch --no-tags --prune --progress --no-recurse-submodules --depth=1 origin +ebc278ec98bb24f2852b61fde2a9bf2e3d83818b:refs/tags/
    # which makes its own local lightweight tag, losing all the annotations in the process. Our earlier script ran:
    #   git fetch --prune --unshallow
    # which doesn't overwrite that tag because that would be destructive.
