When the "package packagename" is missing in the proto file, an error occurs during the invocation.

• I have searched the issues of this repository and believe that this is not a duplicate.

Environment

• Dubbo version: 3.2.7
• Operating System version: macos 13.2.1 (22D68)
• Java version: 1.8

Steps to reproduce this issue

1. proto文件

syntax = "proto3";

option java_multiple_files = true;
option java_package = "org.example.protogen";
option java_outer_classname = "PredictorProto";


message PredictRequest {
  string model = 1;
  string imei = 2;
  repeated string itemId = 3;
}

message PredictResponse {
  string errMsg = 1;
  string model = 2;
  string predictionMap = 3;
}

service PredictService {
  rpc Predict (PredictRequest) returns (PredictResponse) {}
}

2. generate proto files and build a trip server
3. build a native grpc client

Expected Behavior

success

Actual Behavior

failed

If there is an exception, please attach the exception trace:

• native grpc client side:
  

Exception in thread "main" io.grpc.StatusRuntimeException: UNIMPLEMENTED: Service not found:PredictService
	at io.grpc.stub.ClientCalls.toStatusRuntimeException(ClientCalls.java:271)
	at io.grpc.stub.ClientCalls.getUnchecked(ClientCalls.java:252)

原因是在没package xxx;时，会导致Dubbo3TripleGenerator生成的Interface中 SERVICE_NAME错误

Will be fixed in 3.3
