network tutorial: update with rootless cni changes
Starting with podman v3.2 rootless cni will work without the rootless-cni-infra container. Update the network tutorial to reflect the latest changes and mention that the infra container can be removed. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>

+When rootless containers are run with a CNI networking configuration, CNI operations
+will be executed inside an extra network namespace. To join this namespace, use
+`podman unshare --rootless-cni`. Podman version 3.1 and earlier use a special “side-car”
+container called rootless-cni-infra. Do not remove this container while your rootless
+containers are running. If you remove this container (e.g. by accident), all attached
+containers lose network connectivity. In order to restore the network connectivity, all
+containers with networks must be restarted. This will automatically recreate the "side-car"
+container. When you are using version 3.2 or newer the “side-car” container can be
+safely removed. Therefore, it is no longer used.
+For rootfull containers, there is no extra namespace or “side-car” container
as rootfull users have the permissions to create and modify network interfaces on
the host.
