Fix compatibility issue with fastapi >= 0.112.3

    If fastapi is installed we path the method used to build the field definition from model to ensure that the registry is initialized. From version 0.112.3 the patched method 'create_response_field' has been renamed 'create_model_field'. This change ensure that this new method is also patched

    fixes #20
