MangaDex i18n: Add Russian and Spanish translations (#13733)

* Mangadex Spanish translations start

* MangaDex Spanish translations: Settings done

* MangaDex Spanish translation: Content, Format, Genre, Theme done

* MangaDex Spanish translation: rest of setting done

includes Tag Mode, Sort, hasAvailableChapters, unable to process chapter
request, uploaded by $users, and no group

* Android Studio: replace deprecated `capitalize`

uses `replaceFirstChar` as a replacement (honestly suprising how Android
Studio managed that refactor all by itself)

* Add template to fill in Russian translations

* Added MangaDex Russian Translation

* Adding missing Spanish translation for Sort by Rating

and also co-author credit for all the other Spanish translations as well
