Documentation in German only rendered in /en-us/ language namespace

[sypets]

In main en-us branch, the documentation is in German: https://docs.typo3.org/p/dkd/tc-beuser/main/en-us/

Documentation is up to the extension author but this is a public extension. It is very non standard to provide docs only in German and it is wrong, because this is displayed in the en-us namespace /p/dkd/tc-beuser/main/en-us/

Makes it more difficult for people - in general TYPO3 strives to offer documentation in English for the sake of the international community.
