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 core python-librarian-generator Docker image and aligning the development environment to Python 3.14. Additionally, it includes a minor refactoring in the Google Cloud Logging client libraries to streamline how authentication scopes are handled during credential initialization.

Highlights

• Librarian Image Update: The python-librarian-generator Docker image has been updated to a new SHA256 hash, ensuring the use of the latest version of the generator.
• Python Version Upgrade: Development and type-checking configurations have been updated to target Python 3.14, specifically in noxfile.py for the blacken session and in mypy.ini.
• Authentication Refactoring: The Google Cloud Logging client transports (Config, Logging, and Metrics services) have been refactored to explicitly pass authentication scope arguments during credential loading, removing an intermediate scopes_kwargs dictionary.

Code Review

This pull request includes routine updates to Python versions across various configuration files (noxfile.py, mypy.ini) and a Docker image SHA. Additionally, it refactors credential loading in the base.py transport files by explicitly passing scopes and default_scopes instead of using an intermediate scopes_kwargs dictionary. These changes are positive, contributing to better maintainability by keeping dependencies up-to-date and improving code clarity.

The removal of the scopes_kwargs dictionary simplifies the code by eliminating an unnecessary intermediate variable. This improves readability and directly passes the required arguments.
