Mirror images to gcr.io

[ilian]

The builder is currently only published to Docker Hub under the name paketobuildpacks/builder-jammy-base. It is not mirrored to other container image registries like gcr.io as it has been in the past for older images such as gcr.io/paketo-buildpacks/builder:base.
At the time of writing, only gcr.io/paketo-buildpacks/build-jammy-base is mirrored from docker.io/paketobuildpacks/build-jammy-base, but docker.io/paketobuildpacks/builder-jammy-base is not mirroed. Note the difference between build and builder in the image names.

Motivations

Developers might run into rate limits when pulling images from Docker Hub.
