Docker image public availability

[dominikmueller]

Hello,
I would like to know if there is any docker-image publicly available for the tile-generator.
It looks like there is an image on dockerhub: https://hub.docker.com/r/cfplatformeng/tile-generator/tags
But this image doesn't seem to be maintained anymore (last pushed: 2 years ago).

Looking at the ci pipeline, it seems that all current docker images are being pushed to the Google Artifact Registry:
us-west1-docker.pkg.dev/isv-tile-partners/tanzu-isv-engineering/tile-generator
Source: https://github.com/cf-platform-eng/tile-generator/blob/master/ci/pipeline.yml.jinja2#L125-L137

However, these images can't seem to be pulled without authentication
