README: Recommend android.window as Android dependencies

[12people]

There is a desugaring-related bug on Android 12L and Android 13, where an app with desugaring enabled crashes on startup — see this StackOverflow thread.

The fix for this desugaring bug is to add these two dependencies:

implementation 'androidx.window:window:1.0.0'
implementation 'androidx.window:window-java:1.0.0'

It'd be great if flutter_local_notifications recommended these two dependencies in the guidelines on pubdev alongside other necessary desugaring-related Gradle changes.

Thanks for raising this. As this is open-sourced, would you be up for submitting a PR to add this information to the readme?
