feat: Ubuntu 24.04 for 3.0.x release

[mudler]

As ubuntu 24.04 is now out and we already started working on #1792, makes sense to investigate if we can ship 24.04 within a 3.0.x release, or shift 3.1 release items to the next release and cut a 3.1 prematurely

Seems to be working as expected, just waiting on the PR pipelines to see if there are other issues, but I was able to boot at least and I don't see any issues doing systemctl status or a quick view in logs.

tests seem to pass, so I'll move this to done, but feel free to re-open or move to review if you think something is missing
