When the grpc library was updated
GeneratedMessageV3 has been deprecated. link
[Java] The base class for generated messages will be GeneratedMessage, not GeneratedMessageV3.

Armeria's gRPC module depends heavily on grpc-java. We'll probably move on to protobuf 26.0 once grpc-java also moves on.

Even if staying in the same version that grpc-java uses please update the code to remove that GeneratedMessageV3 usage as recommended by grpc-java team here: grpc/grpc-java#11015 (comment)
That would allow an smoother migration path and applications can updated to the latest protobuf libraries and generated code if they want.
