PHP 8.3 warnings

[wp-user-manager]

After upgrading to PHP 8.3 I see more than 35 Deprecated Errors for WP User Manager with the message such as:

1. Creation of dynamic property WPUM\Carbon_Fields\Container\User_Meta_Container::$id is deprecated
2. Calling get_class() without arguments is deprecated
3. Return type of WPUM\Carbon_Fields\Pimple\Container::offsetGet($id) should either be compatible with ArrayAccess::offsetGet(mixed $offset): mixed, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice

We need to see if we can update Carbon Fields safely or patch these issues during our build process
