[FR] "DA" Translations (or/and Swedish/Norwegian)

### Description

As a Dane, I'd love to be able to see the Danish language as an option in AppFlowy.

Translate 80-100% of the application to Danish.

Optionally if you're a Swede or Norwegian, feel free to drop those translations instead!

### Impact

Danish / Scandinavian users
