KDE Gear projects with failing CI (master) (18 March 2025)

[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: 2 repositories were fixed

Bad news: 2 repostories have started failing


cantor - NEW
 * https://invent.kde.org/education/cantor/-/pipelines/913314
  * testpython fails


messagelib - NEW
 * https://invent.kde.org/pim/messagelib/-/pipelines/913049
  * messageviewer-messageparttheme-rendertest  fails


Cheers,
  Albert
