Aurae needs a container registry

[krisnova]

The projects needs a place to store containers, which could implicitly mean the project has an authz/secrets problem as well.

Can we please identify a place for the project to store containers? Can we also work with the other maintainers to make sure folks and the build systems have access to the container registry as needed?

I've been using the GHA package repository for the build image, and I think it might be a good starting place. Auth is relatively simple since its using GHA to push, and its public for anyone who wants to pull the images.
