Feature question - support `--cache-to type=gha[,parameters...]` (GitHub Actions cache) for cache

Description

Docker/Builkit have a very nice option to specify the backend to use for the caching, (E.g. GitHub Action cache), and this makes caching very efficient, as we don't need to store the full storage of buildah.

Would be great to also have this option in buildah, and ideally integrated through redhat-actions/buildah-build

See https://docs.docker.com/build/cache/backends/gha/
