[📚] Expo remote notifications config

Documentation Feedback

This wasn't a huge time-sink for me, but I couldn't find reference on how to enable remote notifications in Xcode if you're using EAS or wanting to use the expo prebuild option. This simply requires adding the following configuration to app.json...

{
    "expo": {
        "ios": {
            "infoPlist": {
                "UIBackgroundModes": ["remote-notification"]
            },
        }
    }
}

Obviously not every project requires remote notifications, so it probably doesn't make sense to add this to the plugin.

More than that - for anything expo can do with built in config powers I'd prefer that there
I think this would be a great addition in the messaging section though - I knew the native part was needed but didn't know how to wire it in with Expo myself either. Maybe a quick Expo-related chunk including this in the iOS setup area for messaging as a docs PR? I'd happily merge anything like that
