Summary of Changes

Hello @parthea, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request primarily focuses on updating the python-librarian-generator image to its latest version, which ensures that the project utilizes the most current tooling. Concurrently, it refactors the credential handling mechanism within the Datastore client transports by streamlining how authentication scopes are passed, leading to cleaner and more direct code for credential management.

Highlights

• Librarian Image Update: The python-librarian-generator image has been updated to a new SHA256 hash in the .librarian/state.yaml file, ensuring the use of the latest version of the generator.
• Credential Handling Refactor: The scopes_kwargs dictionary has been removed from the __init__ methods of DatastoreAdminTransport and DatastoreTransport base classes. Authentication scopes and default_scopes are now passed directly as keyword arguments to google.auth.load_credentials_from_file and google.auth.default functions, simplifying the credential loading logic.

Code Review

This pull request, generated by the librarian tool, updates the generator image and refactors how authentication scopes are handled in the transport base classes. The change removes the scopes_kwargs dictionary and instead passes the scopes and default_scopes arguments explicitly to google.auth functions. This is a good refactoring that improves code readability and maintainability. The changes look correct and I see no issues.
