Subject: [PATCH] docs: cgroup-v1: wrap charge moving deprecation in warning block

Commit 4ddb1a2aa1a3c4 ("docs: cgroup-v1: wrap remaining admonitions in
admonition blocks") in cgroups tree states that it also wraps charge
moving deprecation notice in admonition block (specifically warning).
However, the notice isn't in cgroups tree when the v2 of formatting
improv series [1] is submitted (and then applied), but rather in mm tree
instead.

Wrap the notice to fulfill the intention of referred commit.

 Users can move charges associated with a task along with task migration, that
 is, uncharge task's pages from the old cgroup and charge them to the new cgroup.
