Workflow to sync with Google's repo

This workflow will sync this forked repo with the source one, every Sunday @ midnight ETC.

I'm not sure if the full process will work smoothly. The reason is that a commit to master in this fork will impact the diff between the fork and the source repositories. Any branch out of the master in the fork will contain the action file and potentially appear in future PRs. I would suggest to have this action in a different repository to keep the fork as clean as possible.

My apologies if I might be missing something obvious in the fork sync process as I haven't test myself this kind of scenario

Yeah, I had the same thought but there is a --force flag I didn’t use that would erase all commits no matter if it is behind or ahead. As far as I understood it, without this flag if it's not possible to just sync because there are commits ahead, it will fail.
