Run weekly CI pipelines for each distro that perform initial setup and build everything
For the initial setup we are maintaining a list of packages per distribution to be installed. That list always risks being incomplete and/or outdated.
Instead of hoping random people will encounter and fix issues for their specific distro we should be proactive and regularly test the process ourselves.
Manually testing this is not fun, so we should have automatic CI pipelines that set up kde-builder on a given distro and try to build everything.
https://invent.kde.org/nicolasfella/ksb-ci/ implements such a pipeline. Currently it only covers Ubuntu 23.04, but can be extended to virtually any distro with a docker image available.
Such a pipeline is quite expensive because it builds a lot of stuff, so we wouldn't run this all the time, only in some regular interval (like every 1-n weeks for example)
