Update defvar usage tips example in manual

* doc/lispref/variables.texi (Tips for Defining): Change example
to be about syntax tables instead of old way of defining keymaps
using 'defvar' and 'make-sparse-keymap'.  (Bug#59224)

   When defining and initializing a variable that holds a complicated
-value (such as a keymap with bindings in it), it's best to put the
+value (such as a syntax table for a major mode), it's best to put the
 entire computation of the value into the @code{defvar}, like this:
 
 @example
-(defvar my-mode-map
-  (let ((map (make-sparse-keymap)))
-    (keymap-set map "C-c C-a" 'my-command)
+(defvar my-major-mode-syntax-table
+  (let ((table (make-syntax-table)))
+    (modify-syntax-entry ?# "<" table)
     @dots{}
-    map)
+    table)
   @var{docstring})
 @end example
