[PATCH v2] docs: cgroup-v2: fix misc.events key format description

[Cheng Lingfei via B4 Relay]

From: Cheng Lingfei <chenglingfei@xxxxxxxxxxx>

In misc cgroup, misc.events does not output a simple "max" key. Instead,
each registered misc resource outputs a separate key suffixed with ".max"
(i.e., "<res>.max").
Update the documentation to clarify that the entry key is "<res>.max".

Changes in v2:
- Use "<res>.max" entry name instead of expanding with explicit examples (Michal Koutný).
- Link to v1: https://patch.msgid.link/20260824-master-v1-1-6866b77e1f62@xxxxxxxxxxx
