Update 2023.09.1 (dependency updates)

[caarmen]

• Update dependencies
• Target Android 14
• Gradle conf adjustments:
  • Disable jettifier
  • Adjust jacoco plugin config
• Code fixes:
  • Don't use LiveData Transformations anymore: use the map and switchMap extension functions on LiveData.
  • Fix a nullability error in a LiveData observer type declaration.
  • In SettingsActivity, when loading the voices, load them in a background thread (it seemed slow on Android 14, causing some ANRs).
  • Don't use FLAG_MUTABLE when creating a notification
• Test fixes:
  • Grant the POST_NOTIFICATION permission in the test which attempts to show a notification
  • Use orchestrator (but without clearPackageData). This avoids some ANRs. Using clearPackageData would cause problems with the test speed and calculating coverage.
  • Define android.nonTransitiveRClass=false to be able to access some resource ids from tests (the tests in question should probably be ajusted so we don't need this change).
