Summary

Depends on #2785 (done) and https://github.com/broadinstitute/terra-helmfile/pull/6035 (done) merging first. Once those are complete, we can switch over to only pushing images to the new DSP artifact registry.

This essentially renames the duplicated GHA back to the original version, but keeps all of the newer artifact registry logic.

It is verified that the deployment is now using the new image location:
