Iconpicker Widget wont show on Drupal 10

Adding a path in case somebody needs it before the MR gets merged.

Merged! Thanks!

That was a fast merge! Thanks @Daniel.Moberly!

I think there was a mistake in the JS. There are 3 parameters, but 4 passed in.

(function ($, Drupal, drupalSettings) {
...
})(jQuery, Drupal, drupalSettings, once);
