Push official images to a different registry, in addition to Docker Hub

Problem description

Dockerhub rate limits can prevent pulling image for 6 hours. This is common when running kubernetes and deploying a new cluster.

Feature Request

Push vaultwarden images to an additional registry. e.g. GHCR or Quay

Thanks for all you do on this project.

Is this feature request rejected? I would really appreciate vaultwarden being available from another source.
