docs: Translates an apiserving REST response so it's ready to return.
  
      Currently, the only thing that needs to be fixed here is indentation,
      so it's consistent with what the live app will return.
  
      Args:
        response_body: A string containing the backend response.
  
      Returns:
        A reformatted version of the response JSON.
