Motivation
Our config pages already contains info about headings, we should use them!
Acceptance Criteria
- Using the "Information > Description" and "Information > Licensing" sections of the config files, find any level-2 (==) heading with these labels.
- If found, replaced the contents with {{int:filedesc}} and {{int:license-header}}.
- Keep whitespace formatting intact, as it was on the source wiki. Most notably: Support ==…== as well as == … ==.
- Do not do anything with the "Template" title for now (this is investigated in T198315).
Possible follow-up tasks:
- Detect not only level-2 (==) headings, but any level, as long as it contains one of the labels.
