A complete run through the German docs to test how the prompts work "in production".
gpt-5 found a lot of things which gpt-4o and I have overlooked.
I had to manually modify/fix approximately 10 changes it suggested, which is a good result for 111 files.
The German docs are now completely translated and in sync.
This commit started as an attempt to handle translation of abbr elements, which I was not able to get to work in a clean way. Shortly before I resigned I had the idea to try `openai:gpt-5` as agent in the translate.py, instead of `openai:gpt-4o` and BAM it worked. A lot of other things also worked much better. Modifications had to be made though because GPT-5 interpreted some rules stricter, so some reformulation and some more examples were needed. Will translate with that agent in the remaining translations to test if these prompts work well.
