bug#46926: Remove the quotes from highlighted/linked symbols when displaying docs

Info does not link, but highlight symbols. BTW, why symbols in info are
not linked to their index entries? E.g. the user could press Enter
on a highlighted symbol to quickly look it up. Why isn't this a thing?

Well, is this a symbol?  Example from Elisp info:

‘(DISPLAY PLIST)’

or

‘(:foreground "red" :weight bold)’


These have the face Info-quoted like quoted symbols in Info. So the face
indicates this is a quoted entity (not necessarily a symbol).

If we have a face Info-quoted then there is no need for the quotes, because
the quotes are only text markups which are translated to a face, so the quoted
part is highlighted for the user, there is no point in leaving the markup there.
