openapiv3 tags

After setting the tag, why not overwrite the original default but recreate the tag，
proto file:
```protobuf
service Test {
rpc CreateTest (CreateTestRequest) returns (CreateTestReply) {
option (google.api.http) = {
post: "/api/test",
body: "*"
};
option (openapi.v3.operation) = {
tags: ["TS1"],
};
}
}
```
yaml file:
```yaml
paths:
/api/test:
post:
tags:
- Test
- TS1
..................
```
How do I do it, please, Thanks!
