Accept german translation suggestion for "Set due date"

[jaylinski]

Is your feature request related to a problem? Please describe.

The german translation for "Set due date" is "Ablaufdatum setzen", but should be "Fälligkeitsdatum setzen".

Describe the solution you'd like

Accept this translation suggestion (from 5 years ago):

https://app.transifex.com/nextcloud/nextcloud/translate/#de_DE/tasks/99690055?q=user_suggestions%3Ayes

Describe alternatives you've considered

I'd accept the suggestion, but I don't have the rights in transifex.

Additional context

This is relevant to me, because I'm currently adding the "Reminder" feature, and its reminder-suggestions are affected by the due-date. So this should be correctly translated.
