fix protobuf constraints for old streamlit versions

[ytausch]

Checklist

• Used a static YAML file for the patch if possible (instructions).
• Only wrote code directly into generate_patch_json.py if absolutely necessary.
• Ran pre-commit run -a and ensured all files pass the linting checks.
• Ran python show_diff.py and posted the output as part of the PR.
• Modifications won't affect packages built in the future.

This is a best-effort PR to avoid solving streamlit with newer protobuf versions, based on version constraints used for newer packages.

The current diff generated with show_diff is empty. Is there something I am doing wrong here?
