bug#47363: font locking variable values in Help buffer

[scame via Bug reports for GNU Emacs, the Swiss army knife of text editors]

When inspecting large list values of variables in the Help buffer,
it would make interpreting the list easier if the value had
elisp font lock.

E.g

...
      (cond
       ((eq type 'var)
        font-lock-variable-name-face)
       ((eq type 'type)
        font-lock-type-face)
       ((or
         (not
          (match-string 2))
         (and
          (match-string 2)
          (match-string 4)))
        font-lock-function-name-face)))
    nil t))
  ("^;;;###\\([-a-z]*autoload\\)" 1 font-lock-warning-face prepend)
  ("\\[\\(\\^\\)" 1 font-lock-negation-char-face prepend)
  ("(\\(cl-\\(?:assert\\|check-type\\)\\|error\\|signal\\|user-error\\|warn\\)\\_>"
   (1 font-lock-warning-face))
  (lisp--el-match-keyword . 1)
  ("(\\(catch\\|throw\\|featurep\\|provide\\|require\\)\\_>[ 	']*\\(\\(?:\\sw\\|\\s_\\|\\\\.\\)+\\)?"
   (1 font-lock-keyword-face)
   (2 font-lock-constant-face nil t))
  ("\\\\\\\\\\[\\(\\(?:\\sw\\|\\s_\\|\\\\.\\)+\\)\\]"
   (1 font-lock-constant-face prepend))
  ("\\(\\\\\\)\\([^\"\\]\\)"
   (1
    (elisp--font-lock-backslash)
    prepend))
  ("[`‘]\\(\\(?:\\sw\\|\\s_\\|\\\\.\\)\\(?:\\sw\\|\\s_\\|\\\\.\\)+\\)['’]"
   (1 font-lock-constant-face prepend))
  ("\\_<:\\(?:\\sw\\|\\s_\\|\\\\.\\)+\\_>"
   (0 font-lock-builtin-face))
  ("\\_<\\&\\(?:\\sw\\|\\s_\\|\\\\.\\)+\\_>" . font-lock-type-face)
...

Makes sense to me.  I've now fixed this in Emacs 29.
