• feat: Add Uyghur, Latvian, and Armenian language support in translations LibreChat-AI/librechat.ai#346

This pull request adds support for three new languages—Armenian, Latvian, and Uyghur—across the application's language selector and localization files. The changes include updates to the language selector component, English translations, and the initialization of new translation files for the added languages.

Language support updates:

• Language Selector Component (client/src/components/Nav/SettingsTabs/General/General.tsx):

  • Added Armenian (hy-AM), Latvian (lv-LV), and Uyghur (ug) to the list of selectable languages. [1] [2]

• English Translation File (client/src/locales/en/translation.json):

  • Added English translations for the new languages: Armenian ("Հայերեն"), Latvian ("Latviski"), and Uyghur ("Uyƣur tili").

• Localization Initialization (client/src/locales/i18n.ts):

  • Imported and registered the new translation files (hy, lv, ug) in the localization resources. [1] [2]

• New Translation Files:

  • Created empty translation files for Armenian (client/src/locales/hy/translation.json), Latvian (client/src/locales/lv/translation.json), and Uyghur (client/src/locales/ug/translation.json) as placeholders for future translations.
