OpenAI o1 requires "developer" messages instead of "system" messages

<class 'openai.BadRequestError'> Error code: 400 - {'error': {'message': "Unsupported value: 'messages[0].role' does not support 'system' with this model.", 'type': 'invalid_request_error', 'param': 'messages[0].role', 'code': 'unsupported_value'}}
