The node says

---
They all compare property names using @code{eq}.
---

and plist-member is in that noe, so I think it's covered.  The doc
string of `plist-get' mentions `eq', but the doc string of the other two
don't, so I've now added that in Emacs 28.

In addition, those doc strings (but not `plist-get's) claimed that PROP
has to be a symbol, which isn't strictly true -- it just has to be
something that has a meaningful eq, so it works for (some) numbers, too.
