[NUI] Update InputPanelLanguage enum description (#2770)

- InputPanelLanguage.Alphabet enumeration can be changed
 according to OSD language.
- For instance, if OSD language is not Latin alphabet, such as Korean and Arabic,
 IME default language would change to English.
 If OSD language is Latin alphabet, such as French and Spanish,
 IME default language would be OSD language itself.
