* Como o parâmetro `q` é declarado com `= None`, ele é opcional.
    * Sem o `None` ele poderia ser obrigatório (como o corpo no caso de `PUT`).
* Para requisições `PUT` para `/items/{item_id}`, lerá o corpo como JSON e:
    * Verifica que tem um atributo obrigatório `name` que deve ser `str`.
    * Verifica que tem um atributo obrigatório `price` que deve ser `float`.

* Para requests de tipo `PUT` a `/items/{item_id}` leer el body como JSON:
    * Revisar si tiene un atributo requerido `name` que debe ser un `str`.
    * Revisar si tiene un atributo requerido `price` que debe ser un `float`.
    * Revisar si tiene un atributo opcional `is_offer`, que debe ser un `bool`si está presente.
    * Todo esto funcionaría para objetos JSON profundamente anidados.
