Summary:
we are now uploading the templated YAMLs to GCS, so we should make them available as artifacts in our artifact tracker.
the CLI will download these templates, fill them in, and apply them. this avoids having the CLI generate them unnecessarily. see D7675 for more context.

the next diff will update the artifact job to actually use this new enum.

Test Plan: n/a
