Bug description

The website distribution build's update post-installation notification says You were automatically updated to version (...). But except for nightlies, APK updates aren't automatic:

Signal-Android/app/src/main/java/org/thoughtcrime/securesms/apkupdate/ApkUpdateInstaller.kt

Lines 148 to 149 in 7a66533

	// TODO Auto-updates temporarily restricted to nightlies. Once we have designs for allowing users to opt-out of auto-updates, we can re-enable this
	return Environment.IS_NIGHTLY && Build.VERSION.SDK_INT >= 31 && SignalStore.apkUpdate.autoUpdate && !AppForegroundObserver.isForegrounded()

Steps to reproduce

• Update Signal by tapping the update notification

Actual result: NotificationYou were automatically updated to version (...)
Expected result: Notification You were updated to version (...)
