Add an option in app tu reset push notification service

Product name

Nuki Ios app

Summary

add an option in settings to reset push notifications service

Reason

since the penultimate iOS update, I stopped receiving a lot of notifications. I know we are a few in this case (saw in forums and news websites comments), but apparently not enough for Apple to care about.
In my case, I started receiving some notifications again over time and updated apps, but not from Nuki, unfortunately. I also noticed that for the one app I had the option to reset push notifications services, it worked again right after. Thus, my request !

Examples

A user could use this setting to reset push notifications when they stop working for whatever reason, without having to remove and reinstall the app and re add the lock (which would be complicated without another device or Nuki web access to re invite)
