Code Review

This pull request updates protobuf-java from version 3.25.8 to 4.32.0, which is a major version upgrade. While the gRPC library in use seems to support this new version, the Protobuf-generated Java source files included in the airframe-benchmark module have not been updated. It is crucial to regenerate these files using a protoc version compatible with the new protobuf-java runtime to ensure correctness and avoid potential runtime issues or skewed benchmark results. The existing generated files were created with a much older version.

[gemini-code-assist]

Updating protobuf-java to a new major version (4.x) requires regenerating the Protobuf-generated source files. The existing generated files in airframe-benchmark/src/main/scala/wvlet/airframe/benchmark/http/protojava/ were created with an older protoc version (from grpc-java:1.30.2) and may not be fully compatible with the new runtime. This can lead to runtime errors or incorrect benchmark results.

Please regenerate the .java files from greeter.proto using a protoc compiler version that corresponds to protobuf-java:4.32.0 and include the updated files in this pull request.
