Since 2025.1 testing runtime[1], Ubuntu Noble has been the default distro in testing, but I missed moving the stable/2025.2 and stable/2026.1 grenade jobs to run on Noble; they were still running on Jammy.

I am fixing the nodeset now, which will move grenade jobs on those stable branches on Ubuntu Noble. I am testing those in some of the repos[2], and it seems to be working. I would appreciate if you can test it in your projects and report the issues if any. I will keep the changes open till Friday (March 27th)
