While using reserved PHP keywords as parameter name labels is allowed, in the context of function calls using named parameters in PHP 8.0+, this will easily lead to confusion. To avoid that, it is recommended not to use reserved keywords as function parameter names. This commit: * Renames the `$function` parameter to `$callback` in: * `add_menu_page()` * `add_submenu_page()` * `add_management_page()` * `add_options_page()` * `add_theme_page()` * `add_plugins_page()` * `add_users_page()` * `add_dashboard_page()` * `add_posts_page()` * `add_media_page()` * `add_links_page()` * `add_pages_page()` * `add_comments_page()` * Renames the `$echo` parameter to `$display` in `menu_page_url()`. * Renames the `$parent` parameter to `$parent_page` in `get_admin_page_parent()`.
