docs/scheduler: fix typo and warning in sched-bwc
a) since d73df887b6b8 ("sched/fair: Add document for burstable CFS bandwidth")
[cpu.cfs_quota_us: the total available run-time within a period (in] shoud be removed,
let's delete it.
b) Add a period.
c) fix a build warning:
linux-next/Documentation/scheduler/sched-bwc.rst:243: WARNING: Inline emphasis
start-string without end-string.
