KDE Frameworks with failing CI (kf5) (3 March 2024)

[Albert Astals Cid]

Please work on fixing them, otherwise i will remove the failing CI jobs on 
their 4th failing week, it is very important that CI is passing for multiple 
reasons.

Good news: 1 repository was fixed

Bad news: 1 NEW repository is failing

syntax-highlighting
 * https://invent.kde.org/frameworks/syntax-highlighting/-/pipelines/620988
  * testhighlighter_test and htmlhighlighter_test fail on Linux


Cheers,
  Albert
