Enable use of gradle for all image builds for publishing, eliminating the per-image build action in docker-unified.yml that duplicated what was in gradle but used slightly different mechanisms to determine what is the tag. Enabled gradle build to consume tags provided by the workflow and produce tags same as earlier.
Use bake matrix builds to build slim/full versions of datahub-ingestion, datahub-actions.
Publish images and scan relies on gradle to get the list of images, via depot.
Image publish and scans run once a day on schedule or on manual triggers only.
Pending work: Separate the publish and scans into a separate workflow that runs on a schedule and could also run other tests.
