Code Review

This pull request introduces several new workspace branch management features to the Dataform v1beta1 API, including methods to sync workspace refs, fetch workspace branches, delete branches, checkout workspace branches, and fetch the current workspace branch. It also adds corresponding request/response messages, client settings, stub implementations, unit tests, and generated code samples. Additionally, the Workspace message is updated with fields for branch management, original branch, and clone depth. In the Dataform v1 API, a lineage_enabled field is added to CodeCompilationConfig. Finally, the Go package path is updated in the Developer Knowledge v1 proto, and the googleapis dependency commit is bumped in librarian.yaml. I have no feedback to provide as there are no review comments to assess.
