Update guidance for using object names in titles

[daobrien]

Initial question from @nmuller66

Do we have the guidance about avoiding object names in headings documented anywhere?
Examples:
Virt-Launcher Pods
PersistentVolumes
PersistentVolumeClaims

Initial suggestion from @daobrien

I'd hazard a guess that almost all of those have a simple "plain English" description that could be used in a title. There might be exceptions (aren't there always?) but I'd need a better look at the content to offer suggestions. I don't see any issue with "Persistent Volumes" or "Persistent Volume Claims"; you'd only use the one-word forms when referring to the actual objects, not the concept.

https://stylepedia.net/style/5.1/#heading-styles > File Names, Commands, and Related Terms goes some way towards addressing this. We could probably just expand it with more examples.
