KDE Gear projects with failing CI (master) (17 June 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: 1 repo fixed

Bad news: 1 repo still failing, 1 new repo failing

cantor - 3rd week
 * https://invent.kde.org/education/cantor/-/pipelines/974444
  * testmaxima fails


gwenview - NEW
 * https://invent.kde.org/graphics/gwenview/-/pipelines/974445
  * nasa does not let us download stuff and flatpak fails


Cheers,
  Albert
