`ComicInfo.xml` files only use the first description returned (which may be a different language)

[FibreTTP]

What happened ?

MangaDex supports multiple descriptions for a manga, which are mainly used for alternative languages. They are (probably) returned by the API in the order of their key, which means descriptions with a language code sorted above "en" alphabetically will be first, and thus be the one used in ComicInfo.xml files written.

The language codes are defined here: https://api.mangadex.org/docs/3-enumerations/#language-codes--localization

This does not affect manga_info files.

Examples:

ComicInfo.xml
