[Feature request] Push image to ghcr.io

[iptizer]

Description:

• Pulling the image from Kubernetes seems still to be not possible.
• We only got this working using the "new" GitHub packages platform "ghcr.io", see announcement
• Using this new platform pulling with Kubernetes is possible.
• Using this service currently requires to pull&push to local repo, which is additional effort.

Request:

• Push images also to https://ghcr.io - aka - provide images in ghcr

Can we close it?
