I found a bug about postman examples

thanks for reporting, yeah that does not look right. please note that you don't need to use the HTTP Gateway to use SpiceDB if you are using Postman: Postman supports gRPC reflection, so you can discover RPC methods and invoke them from Postman. I understand the HTTP examples are useful to understand the API.

aha, actually I didn't use postman rpc funcion, because high version postman doesn't support local dashboard, everything must online, that's very terrible

I don't know wat high version is, but fine
