wp_get_nav_menu_items using old syntax

[evandentremont]

In nav-menu.php, function wp_get_nav_menu_items()

if ( count( $items ) > 1 )
	$args['include'] = implode( ',', $items );
else
	$args['include'] = $items[0];

can be replaced by

$args['include'] = items;

"Beginning with Version 3.0, an array of Page ID also can be used." I presume that applies to posts as well since posts page says to "See also get_pages() for example parameter usage."

Updated args to send array value for include parameter

Updated argument works fine, tested on a new setup.

Simplify the setting of $args['include'] in wp_get_nav_menu_items().

Props UmeshSingla.
Fixes #28515.
