Missing schema for views.filter.filter_id.expose.reduce

See this issue: https://www.drupal.org/project/drupal/issues/3299930 →

Probably, there was a misconfiguration on your custom view.

After installing the module Config inspector we get the following message:

"'reduce' is not a supported key."

After review that verf view filter \Drupal\verf\Plugin\views\filter\EntityReference extends from \Drupal\views\Plugin\views\filter\InOperator, the schema also should be "views.filter.in_operator".

Also, the "show_unpublished" is defined on the filter and should be added to the schema.

Ready to review!!
