Code Review

This PR updates the protobuf dependency to v6 across multiple Python projects. The update seems straightforward, but it's important to ensure that all projects are compatible with the new version and that no regressions are introduced.

Summary of Findings

• Compatibility with protobuf v6: The protobuf library has been updated from v4/v5 to v6. It's crucial to verify that all code using protobuf is compatible with the new version. This includes checking for any breaking changes or deprecated features that may affect the functionality of the affected projects.
• Testing with protobuf v6: It's important to run tests to ensure that the updated protobuf dependency does not introduce any regressions or compatibility issues. The existing tests should be sufficient, but it's worth considering adding new tests specifically for protobuf v6 if there are any known compatibility concerns.

Merge Readiness

The PR updates the protobuf dependency across multiple projects. While the changes themselves are simple, it's crucial to ensure compatibility with the new version and that no regressions are introduced. I recommend running thorough tests on all affected projects before merging. I am unable to approve this pull request, and users should have others review and approve this code before merging.
