Could you create a proper PR? The current german translation was created from the community with the help of my weblate instance (See #5). Feel free to use my weblate instance to adjust or extend the translation. Otherwise, I will look at your changes as soon as I got time for it. I also want to improve the current translation to the latest changes, but I don't have the time currently.
