[PATCH] sched_deadline, docs: fix cpuset example for cgroupv2

[Matteo Martelli <matteo.martelli@codethink.co.uk>]

Documenation/scheduler/sched-deadline.rst provides two examples for how
to setup cgroup and cpuset for deadline tasks: one for cgroup v1 and one
cgroup v2. The code block in the latter is not properly html rendered as
the :: marker is missing.

Add the :: marker before the code block for the cgroup v2 example to fix
html rendering.

Also make the example description more explicit for better clarity.

 5.2 Using cgroup v2 cpuset controller
