* Prüfen, ob es einen optionalen Abfrageparameter namens `q` (wie in `http://127.0.0.1:8000/items/foo?q=somequery`) für `GET`-Anfragen gibt.
    * Da der `q`-Parameter mit `= None` deklariert ist, ist er optional.
    * Ohne das `None` wäre er erforderlich (wie der Body im Fall von `PUT`).
* Bei `PUT`-Anfragen an `/items/{item_id}` den Body als JSON lesen:
    * Prüfen, ob er ein erforderliches Attribut `name` hat, das ein `str` sein muss.

Wir können das alles deklarieren, ohne den ursprünglichen `APIRouter` ändern zu müssen, indem wir diese Parameter an `app.include_router()` übergeben:
