docs/scheduler/sched-design-CFS: formatting fix

Fix the rendering of the paragraph. Before the fix, the first line is
rendered in bold (I'm not quite sure why) and is also separated from the

 CFS's task picking logic is based on this p->se.vruntime value and it is thus
 very simple: it always tries to run the task with the smallest p->se.vruntime
