Treat response content_type */* as application/json

[781574155]

most of the time, openapi use json as response. so i wish you treat */* as application/json, insteat of response will be omitted from generated client
I use springboot framework. It can reponse different content type base on the accept header of the client request. so in the openapi doc, it's response content will be */*

Or add a command line switch param to support this

content_type_overrides:
  '*/*': application/json

this works for me!
