significan:

* Partiendo en el mismo paquete en el que este módulo (el archivo `app/routers/items.py`) habita (el directorio `app/routers/`)...
* ve al paquete padre (el directorio `app/`)...
* y allí, busca el módulo `dependencies` (el archivo en `app/dependencies.py`)...
* y de él, importa la función `get_token_header`.

¡Eso funciona correctamente! 🎉
