Subject: [PATCH] Add UI Automator test for verifying 'Commons' app language
 option in system settings

This commit introduces a UI Automator test in the 'AppLanguagesSystemTest.java' file under the 'fr.free.nrw.commons.ui' package. The test verifies the following:
- Navigates through Android system settings.
- Scrolls to and selects 'Languages & input'.
- Opens 'App languages' and checks if the 'Commons' app appears in the list.
The test uses UiScrollable and UiSelector to find and interact with system UI elements.
