rules_proto_grpc_java generates V2 proto code instead V3

[jduan-highnote]

Issue Description

I tried out the provided java example here https://github.com/rules-proto-grpc/rules_proto_grpc/blob/master/examples/java/java_grpc_compile/BUILD.bazel and bazel build thing_java_grpc generated java code that extends com.google.protobuf.GeneratedMessage which is old. It should have generated Java code that extends com.google.protobuf.GeneratedMessageV3.
