https://github.com/rancher-sandbox/rancher-desktop-opensuse/blob/04130ae51aa8ec6c078f6da728a11a7220307908/root/usr/local/lib/systemd/system/lima-init.service is currently not run inside the network namespace; this causes things like downloading k3s to fail.

It should get an unit drop-in to set it, like https://github.com/rancher-sandbox/rancher-desktop-opensuse/blob/04130ae51aa8ec6c078f6da728a11a7220307908/root/usr/local/lib/systemd/system/containerd.service.d/network-namespace.conf does (by running the command under wsl-exec).

The bulk of the task here is to check that things work correctly.
