I added the german translation for the settings menu :)

Hi,

I just read your stance on translations and understand that contributions are usually handled via OneSky. However, it seems that the OneSky translation project is no longer accessible.

To ensure the German translation is accurate, I have reviewed the existing translation and compared it to the en_us.json file using an AI:

Consistency: The translation aligns with the original structure and meaning of en_us.json.
Technical Terms: Key terms such as "Chunk", "V-Sync", and "FPS" are either appropriately translated or kept in English for clarity.
Contextual Accuracy: The translation considers the intended context within the game’s settings and options.
Language Fluency: Proper grammar and vocabulary ensure a clear and natural reading experience for German-speaking users.

I would be happy to contribute to the translation in an alternative way.

Kind regards,
Rafmon
