Translation update needed for HTTP headers, meta elements and language information

Apologies if i already mentioned this, and apologies if i forgot to 
mention it.

Some time ago, the article

HTTP headers, meta elements and language information
https://w3c.github.io/i18n-drafts/questions/qa-http-and-lang.en

was substantially changed.  See the commit logs dating back to 2019 at
https://github.com/w3c/i18n-drafts/commits/gh-pages/questions/qa-http-and-lang.en.html

I would be grateful if the following could be retranslated:

HTTP-Header, Meta-Elemente und Sprachinformationen
https://w3c.github.io/i18n-drafts/questions/qa-http-and-lang.de

Note that some of the original material in that page has now been moved to

Types of language declaration
https://w3c.github.io/i18n-drafts/questions/qa-text-processing-vs-metadata.en



thank you,
