Support Facets 3 - currently does not work for taxonomy term reference exposed filter

@aaronbauman - this sounds like this issue:
"The submitted value [value] in the [name] element is not allowed."
https://www.drupal.org/project/facets/issues/3446040 🐛 The submitted value [value] in the [name] element is not allowed. Active

For which MR!286 therein fixed it for me.
https://www.drupal.org/project/facets/issues/3446040#comment-15978070 🐛 The submitted value [value] in the [name] element is not allowed. Active

I'm also using facets 3.0, select2 with taxonomy term references.

The changes in 3446040 look pretty significant.

I was able to work around the bug with a form alter.
I'll stick with until the patch has some more reviews or tests.

 function MY_MODULE_form_alter(&$form, FormStateInterface $form_state, $form_id) {
  if ($form_id == 'views_exposed_form' && !empty($form['#context']['bef'])) {
    // Facets 3.x + Select2 + BEF causes problems with validation.
    // Remove validation here for that scenario.
    foreach ($form['#info'] as $name => $element) {
      if (!str_starts_with($name, 'filter-facets')) {
        continue;
      }
      $key = $element['value'];
      $form[$key]['#process'][] = 'facets_exposed_filters_remove_validation';
    }
  }
