Loosen GRPC requirements.

[tvalentyn]

Context: We discovered that Go precommit suite was failing (#32324) after GRPC 1.66 update (grpc/grpc#37710).

GRPC team believes that this error is triggered by a somewhat specific usage scenario in the Go postcommit suite, caused by the suite running multiple go tests in parallel and there is not sufficient reason to believe that Beam users would also be affected (cc: @sergiitk to keep me honest).

On the other hand, Beam users are adversely affected by a capped lower bound on grpcio. We still anticipate a proper fix in grpc/grpc#37710, and it might arrive in grpcio==1.72.2. However, given that grpcio==1.72.1 was yanked, we are proceeding with removing the grpc lower bound to ensure that Beam users have a compatible grpc requirement in Beam 2.72.0. Out of caution, we are not planning to update GRPCIO in the default beam SDK containers in 2.72.0, keeping them on 1.65.x. Beam users would be able to install newer versions of GRPCIO though.

Some confidence in this approach is that Beam Python 3.13 users have been on newer versions on GRPC and we are not aware of issues.

GRPC version 1.70.x and earlier are affected by a known issue grpc/grpc#38290 (comment) , hence keeping those out of the allowed range.

Summary of Changes

Hello, 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 addresses grpcio dependency management by modifying the setup.py file to broaden the acceptable range of grpcio versions for Beam users. The change aims to improve compatibility and flexibility for users installing newer grpcio releases, while carefully maintaining exclusions for versions known to have issues. This consolidation simplifies dependency declarations and mitigates problems encountered with specific grpcio updates.

Highlights

• Relaxed GRPC Version Constraints: The grpcio dependency in sdks/python/setup.py has been updated to remove specific version exclusions for 1.71.x through 1.78.0. This change allows Beam users to install a wider range of newer grpcio versions, addressing issues with recent releases and a yanked version (1.72.1).
• Consolidated Python Version Support: The separate grpcio dependency specification previously defined for Python 3.13+ has been removed. The grpcio requirement is now consolidated into a single entry that applies across all supported Python versions.
• Continued Exclusion of Problematic Versions: Despite the loosening of constraints, known problematic grpcio versions, including 1.70.x and earlier specific versions (e.g., 1.48.0, 1.59.* to 1.69.*), remain explicitly excluded to prevent known compatibility issues.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.
