Para eso, actualizamos el modelo de Pydantic `TokenData` con una nueva propiedad `scopes`.

Al validar los datos con Pydantic podemos asegurarnos de que tenemos, por ejemplo, exactamente una `list` de `str` con los scopes y un `str` con el `username`.

Another big feature needed by APIs is data validation, making sure that the data is valid, given certain parameters. For example, that some field is an `int`, and not some random string. This is especially useful for incoming data.

Without a data validation system, you would have to do all the checks by hand, in code.
