Andrea pointed out that we can and should be using Ubuntu 22.04.
Unfortunately it still doesn't ship some of the deps we need like
clang-17, but it does at least ship virtme-ng, so it's good for us to
use this so that we can actually test running the schedulers in a
virtme-ng VM when it supports being run in docker.
Also, update the job to run on pushes, and not just when a PR is opened

When Ubuntu ships with sched_ext, we can also maybe test loading the
schedulers (not sure if the runners can run as root though). For now, we
should at least have a CI job that lets us verify that the schedulers
can _build_. To that end, this patch adds a basic CI action that builds
the schedulers.
As is, this is a bit brittle in that we're having to manually download
and install a few dependencies. I don't see a better way for now without
hosting our own runners with our own containers, but that's a bigger
investment. For now, hopefully this will get us _some_ coverage.
