Please fix PHP 8.2 deprecated notices

PHP Deprecated:? Creation of dynamic property UserOnline_Admin_Integration::$nonce is deprecated in ?/wp-content/plugins/wp-useronline/scb/AdminPage.php on line 527

PHP Deprecated:? Creation of dynamic property UserOnline_Admin_Integration::$file is deprecated in /wp-content/plugins/wp-useronline/scb/AdminPage.php on line 138

Getting these two when using your plugin with PHP 8.2. Please explicitly define these properties at the beginning of the class “scbAdminPage” by adding these lines:

public $nonce;
public $file;

In this file /wp-content/plugins/wp-useronline/scb/AdminPage.php. You can add them right below Line 35 which defines:

protected $textdomain;
