docs: cgroup-v2: fix misc.events key format descriptiongrafted
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".
