KDE Frameworks with failing CI (master) (4 January 2026)

[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.

Bad news: 1 keeps failing

kcalendarcore - 2nd week
 * https://invent.kde.org/frameworks/kcalendarcore/-/pipelines/1126565
  * Qt 6.11 fails, possible regression?

Cheers,
  Albert
