replaces the default (pasta) with slirp4netns in the podman container.
This is a workaround to allow using the container when offline.
Note that this actually degrades network peformance for the container,
so it should be removed once the fix for pasta/podman is eventually implemented.
See: containers/podman#23566
Note that this requires the host system to have slirp4netns installed
on fedora you can do this via
dnf install slirp4netns
