    to generate the artifacts and upload the files in the artifacts folder
    to the draft release.

  git tag -s $VERSION
  and inserts the changelog into the tag description.
  To perform this step, you need a PGP key registered on github.
• An OWNER pushes the tag with
  git push $VERSION
  • Triggers prow to build and publish a staging container image
    gcr.io/k8s-staging-lws/lws:$VERSION

  updating k8s.gcr.io/images/k8s-staging-lws/images.yaml to
  promote the container images

  in main branch:
• For a major or minor release, create an unannotated devel tag in the
  main branch, on the first commit that gets merged after the release
  branch has been created (presumably the README update commit above), and, push the tag:
  DEVEL=v0.$(($MAJ+1)).0-devel; git tag $DEVEL main && git push $DEVEL
  This ensures that the devel builds on the main branch will have a meaningful version number.
