Associate the release publishing with an environment so we can lock down the refs that are allowed to do so.
Allow maximum of 30 minutes to publish (longest I could see was 11 minutes).
- Wait for the image to be mirrored after publish. - Parameterise some things. - Add TODO regarding attestation and signing.
Add steps to verify the container image's attestation and signature immediately after they are created.
Don't verify nothing.
