Update the usePermission hook to render correctly on iOS 16.4

[jasikpark]

Description

Before this change, the state of the notification permission status on iOS would not be rendered correctly after enabling it.

This PR refactors the usePermission hook to subscribe to the notification permissions correctly

Annoyingly, this isn't the entirety of why iOS notifications aren't working yet...
