Make sure the description from responses is also generated as a comment

In some openapi specifications there are descriptions for the various responses, like in:

        "responses":{
          "200":{
            "description":"The posted JWT is valid. Responds with access token",
            "content":{
              "application/json":{
                "schema":{
                  "$ref":"#/components/schemas/AccessTokenResponse"
                }
              }
            }
          },
          "400":{
            "description":"The posted JWT is invalid.",
            "content":{
              "application/json":{
                "schema":{
                  "$ref":"#/components/schemas/AccessTokenRequestFailedResponse"
                }
              }
            }
          }

These are, however, lost when generating the response class.
