man/systemd-nspawn: call dnf with --use-host-config

This is needed for dnf5. But dnf-4 doesn't know about it. So also add a hint to
skip the option with dnf-4. We can drop this later when dnf5 is the default
everywhere.

Also, s/vim-minimal/nano/. Nano is the default editor in Fedora since
https://fedoraproject.org/wiki/Changes/UseNanoByDefault.

This installs a minimal Fedora distribution into the directory
<filename index="false">/var/lib/machines/f&fedora_latest_version;</filename>
and then boots that OS in a namespace container. Because the installation
is located underneath the standard <filename>/var/lib/machines/</filename>
