Dieser Parameter erstellt nicht diesen Endpunkt / diese *Pfadoperation*, sondern deklariert, dass die URL `/token` diejenige sein wird, die der Client verwenden soll, um den Token abzurufen. Diese Information wird in OpenAPI und dann in den interaktiven API-Dokumentationssystemen verwendet.

Wir werden demnächst auch die eigentliche Pfadoperation erstellen.
