Add Android 14 physical devices to firebase tests (#136736)

I've been keeping an eye on the device list, and android 14 devices recently became available. For reviewing purposes (and anyone who comes across this in the future), you can check the available devices here at the third option without needing a firebase login:
https://firebase.google.com/docs/test-lab/android/available-testing-devices

The "shiba" device is high capacity. There are no api 34 virtual devices yet.
