ios deps: Use PushNotificationIOS from react-native-community, not RN…

… core.

In a recent commit, we asked RN's PushNotificationIOS to take
responsibilities that were previously taken by
wix/react-native-notifications, and removed the Wix library.

Now, we account for the fact that PushNotificationsIOS from RN is
deprecated [1] and asks us to use
@react-native-community/push-notification-ios instead. So, do.

These were my steps:

1. Use the setup instructions for `PushNotificationIOS` [1] from RN
   v0.62 to tear it down.

2. Follow the setup instructions for
   @react-native-community/push-notification-ios at the latest,
   v1.5.0 [2]. The native code closely matches what was there
   before, which makes sense. There are a few additions, and notes
   on old iOS APIs. We no longer support iOS 10, so we leave out
   some methods that target iOS <=10.

3. Follow the simple "Migrating..." instructions [3] that say you
   just have to change the imports; no call site changes are
   necessary.

4. Change a few comments that refer to details of the directory
   structure or implementation of the library.

5. Test thoroughly, as in the previous commit, and observe the same
   results.
