Label Request

We kindly request that the translation label be added to this pull request. Unfortunately, we cannot apply it ourselves due to missing write access on the repository.

1. Version on the cover page says "2.0" It should be "2025"
2. Revision history should be updated adding the German revision after the original English revision.

[Setotet]

Please squash the commits to one commit before merge.

[Setotet]

Three check points:

1. paragraph spacing
2. "#" or "Nr" after "Szenario"
3. NB_SPACE usage after ###$
   Not all instances are commented; pls be comprehensive.

My last two commennts:

1. 2025-01-13 for German release date
2. Unnecessary new line in LLM06.
   Otherwise, LGTM.

FYI -- How to remove appendices
Remove doc_appendix_titles in custom_data_LLM_de-DE.json:

"doc_appendix_titles": [
        ""
    ]

or
"doc_appendix_titles": []
