Actualiza `get_current_user` para recibir el mismo token que antes, pero esta vez, usando tokens JWT.

Decodifica el token recibido, verifícalo y devuelve el usuario actual.

Si el token es inválido, devuelve un error HTTP de inmediato.

## Actualizar la *path operation* `/token`

Crea un `timedelta` con el tiempo de expiración del token.

Apenas com esse declaração de tipos do Python, o **FastAPI** irá:

* Ler o corpo da requisição como um JSON.
* Converter os tipos correspondentes (se necessário).
* Validar os dados.
    * Se algum dados for inválido, irá retornar um erro bem claro, indicando exatamente onde e o que está incorreto.
* Entregar a você a informação recebida no parâmetro `item`.
