🐞 Description of the bug

API models that use Enums are not supported properly at present, they present as strings and end up raising an assertion error.

  File "C:/git/demo.py", line 48, in <module>
    info_result = info_client.info_get()
  File "C:\git\openapi\api\info_api.py", line 101, in info_get
    (data) = self.info_get_with_http_info(**kwargs)  # noqa: E501
  File "C:\git\openapi\api\info_api.py", line 146, in info_get_with_http_info
    return self.api_client.call_api(
  File "C:\git\venv\lib\site-packages\ansys\openapi\common\_api_client.py", line 432, in call_api
    return self.__call_api(
  File "C:\git\venv\lib\site-packages\ansys\openapi\common\_api_client.py", line 183, in __call_api
    return_data = self.deserialize(response_data, response_type)
  File "C:\git\venv\lib\site-packages\ansys\openapi\common\_api_client.py", line 330, in deserialize
    return self.__deserialize(data, response_type)
  File "C:\git\venv\lib\site-packages\ansys\openapi\common\_api_client.py", line 377, in __deserialize
    return self.__deserialize_model(data, klass)
  File "C:\git\venv\lib\site-packages\ansys\openapi\common\_api_client.py", line 820, in __deserialize_model
    kwargs[attr] = self.__deserialize(value, attr_type)
  File "C:\git\venv\lib\site-packages\ansys\openapi\common\_api_client.py", line 376, in __deserialize
    assert isinstance(data, dict)
AssertionError

We need to revisit the necessary fixes for MYPY to make sure that we're not being overzealous.

📝 Steps to reproduce

Generate a client with an enum property, calls to an endpoint that returns that model will fail with the given AssertionError above
