[Doc] Add example run command with cgroup support (#1752) 

Adds an example command to launch processes via systemd-run into a
dedicated systemd scope within the users slice, which allows using
systemd-oomd, that evaluates memory consumption on a per cgroup basis.

The systemd-run arguments are chosen in alignment with systemds
desktop environment integration recommendations¹.
