Feat: Libretranslate(New Translator)

[penginn-net]

What

翻訳の種類にセルフホスト可能な機械翻訳API、Libretranslateを追加しました
https://github.com/LibreTranslate/LibreTranslate

Why

外部サービスを利用する翻訳はレートリミットや従量課金に影響されるため、ユーザに向けて提供しずらいです。
そのため、セルフホスト型翻訳APIを追加して管理者が翻訳機能をより提供しやすくします

Additional info (optional)

Api Endpoint: http://translator:5000
