bug#50759: 26.3; Add `Look Up Symbol (Code Name) in Manual' to Help > Search Documentation menu

[Drew Adams]

Enhancement request.

Please consider adding a menu item for `C-h S' (`info-lookup-symbol') to
the Help > Search Documentation menu-bar menu.

The menu-item name is up to you.  Using "Symbol" in the name has
advantages and disadvantages.  Disadvantage: it likely won't be clear to
some what's meant.  Advantage: trying it is a good way to discover what
"symbol" means for Emacs.
