Remove /install/vm
Since we're dropping support for VirtualBox (#20241), virtual machines are only
documented for Linux users now.
Furthermore, GNOME Boxes only works with ISO images, while virt-manager works
much better with USB images, so the simplification that we've used so far of
pointing virtual machines people to ISO image is not so good anymore.
Instead, let's rely on /doc/advanced_topics/virtualization to orient these few
Linux users rather than having a dedicated page about VMs as part of /install.
