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".

+	  This option provides support for the IndustryPack framework.  There
+	  are IndustryPack carrier boards, which interface another bus (such as
+	  PCI) to an IndustryPack bus, and IndustryPack modules, that are
+	  hosted on these buses.  While IndustryPack modules can provide a
+	  large variety of functionality, they are most often found in
+	  industrial control applications.
