bazel: Add comment for public protoc plugin

The 3rd-party rules_proto project is referencing our compiler directly and not using our java_grpc_library. This target is fine for them to use (although we'd prefer using our java_grpc_library), but most users shouldn't be touching it. Related to #5942 and #5947
