De esta manera puedes añadir anotaciones de tipos correctas a tus funciones incluso cuando estás devolviendo un tipo diferente al modelo de response, para ser utilizado por el editor y herramientas como mypy. Y aún así puedes hacer que FastAPI realice la validación de datos, documentación, etc. usando el `response_model`.
