Rename POST_NOTIFICATION to POST_NOTIFICATIONS (#35533)

Summary:
After adding `<uses-permission android:name="android.permission.POST_NOTIFICATIONS"/>` on my `AndroidManifest.xml`, I expected to use `PermissionsAndroid.PERMISSIONS.POST_NOTIFICATIONS` but `POST_NOTIFICATIONS` is `undefined` and is named `POST_NOTIFICATION` instead.

Every other Android permission is 1:1 in spelling except this one where it lacks `S`.

Not sure if this is a welcome change since this can be breaking. Or maybe we can include both with and without `S` to not be a breaking change. Or just keep it as is and close this PR.
