doc: quote list items in POD

Recent versions of Pod::Simple complain if we use integers or other
special characters in an =item list. We have a couple bulleted lists
that happen to have integers or other special characters as the list
values. Quote the items with C<> so that Pod::Simple can correctly parse
them again.
