wp_nav_menu_remove_menu_item_has_children_class()WP 6.2.0

Remove the menu-item-has-children class from bottom level menu items.

This runs on the nav_menu_css_class filter. The $args and $depth parameters were added after the filter was originally introduced in WordPress 3.0.0 so this needs to allow for cases in which the filter is called without them.
