PHP 8.5 Deprecated warning

For some other testings, i switched on Debug log. I found issues with admin edtior too:

PHP Deprecated: Using null as an array offset is deprecated, use an empty string instead in /wp-content/plugins/admin-menu-editor/includes/menu-item.php on line 284

AI says there would be a simple solution (in line 284?):

$key = $key ?? '';
$value = $array[$key] ?? null;

instead of only $value = $array[$key];

Would be nice if this plugin gets fully php 8.5 functional.
