Bug: Localized titles do not work on Android (Language + Country)

### Tested versions

I tested this example on Godot 4.5 but it also works on Godot 4.6

Tested with Android 15

### System information

Godot 4.5, Godot 4.6, Android 15,

### Issue description

I just discovered a bug while trying to create titles for my games and applications with a local title (language + country), but the problem is that it doesn't work on Android. Only the language works, not the country. For example, I created an example with the game MyGame, which I renamed Great Game in American English (en_US). The MyGame game works for all other languages, but when I set the system language to American English, it still displays MyGame instead of Great Game.



### Steps to reproduce

Enter a local title (language + country) and when exporting to Android with the respective language you have chosen as the localized title (en_US, fr_CA, en_GB or any other language variety) the International title appears.
