Branching process involves a manual creation of a branch in private "10gen/mongo" repo. It was expected that copybara would be able to create the same branch in public "mongodb/mongo" repo, but during v7.3 branching copybara wasn't able to do that.

Therefore v7.3 branch was created in public "mongodb/mongo" repo manually too.
We need to make copybara creating a new branch, so that we don't have to create the branch manually in public repo.
