SUMMARY
Google Cloud does not host source repositories anymore, they provide connections to other source code providers (e.g. github, gitlab, bitbucket)
Likewise, they stopped offering their ML products in favor of Vertex AI.
The modules that use these APIs are currently broken and, given that the upstream actively discourages you to use them, are not worth to fix imo.
There should be some new modules to replace sourcerepo_repository under the cloudbuild umbrella (since they are part of the v2 API) and there should be new modules for Vertex as well.
After the next major version, these should be tombstoned, ref:
