The pipeline is broken into two. The first one is to be triggered when the public repo is tagged. It then tags the private repo, builds and upload the builder and base images, and push a new commit to the release (merged repo). This pipeline also does text manipulation on several files in the release repo to ensure that the images uploaded in this pipeline is always used to reproducibly build the release repo at the same commit.
The second pipeline is then triggered by commit into the release repo, which builds, signs and uploads the proxy image.
Also updated the dependency lock files to use the latest plugins dependencies, which are uploaded to the GCS repo.
