Summary of Changes

Hello @tarun-google, 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 maintaining the project's Python dependency ecosystem. It introduces xds-protos to enable support for Envoy API protobufs, which is a significant functional addition for Python 3.13. Concurrently, it performs a comprehensive update of existing Python package versions across all supported Python environments and specialized ML/GPU configurations, ensuring the project benefits from the latest features, bug fixes, and security patches from its underlying libraries.

Highlights

• New Dependency xds-protos: The xds-protos package has been added as a new dependency, specifically for Python 3.13 environments, to support Envoy API proto functionality.
• Dependency Updates: Numerous Python dependencies across various requirements.txt files (for Python 3.10, 3.11, 3.12, 3.13, and different environments like ML and GPU) have been updated to their latest versions. These updates include packages like beartype, cachetools, google-cloud-* libraries, opentelemetry-* packages, and many others.
• License Information: License and notice URLs for the newly added xds-protos dependency have been included in dep_urls_py.yaml.
