Summary
Copy signed released image from GCR to GHCR using cosign cli copy command.
This will ensure the signature will be the same between the two registry.
@cpanato I had to plumb a new GITHUB_USER env var to allow docker auth to copy image from GCR to GHCR. Not sure if there is a better way or not. Please take a look.
