tests: k0s: Always use latest version, apart from CRI-O tests

We've been pinning a specific version of k0s for CRI-O tests, which may
make sense for CRI-O, but doesn't make sense at all when it comes to
testing that we can install kata-deploy on latest k0s (and currently our
test for that is broken).

Let's bump to the latest, and from this point we start debugging,
instead of debugging on an ancient version of the project.
