Need to add NSBluetoothAlwaysUsageDescription for iOS 13

you --> your

Change the title of the permission `mediaLibrary` to "Media Library".

I recently got issue in some version of iOS (apparently 10?) with this key missing.
Not sure why I needed that but as it feel redundant with the key below, but this avoid some crashes I found with sentry :)

react-native CLI is the modern way to go and should be encouraged.
