test: Add regression tests for protobuf >= 7.34.0 compatibility (#6435) by Jwrede · Pull Request #6450 · feast-dev/feast

…t-dev#6435)

PR feast-dev#6015 replaced MessageToDict with a custom dict builder in
feature_server.py, which incidentally fixed the crash caused by the
removed float_precision kwarg in protobuf >= 7.34.0.

Add explicit regression tests to prevent reintroduction:
- Verify convert_response_to_dict never calls MessageToDict
- Verify double precision round-trips without float_precision kwarg

Fixes feast-dev#6435
