BREAKING CHANGE FOR DRUPAL 9 SITES I updated the API path that is queried to fetch Drupal blocks. From now on we'll query `/admin/content/block/:id` which will break for Drupal 9 sites. If you do want this to work for Drupal 9 sites you can add the `DRUPAL_9` property to your `react-global-configuration` object for backwards compatibility. Make the value of that property a boolean of `true`. For Drupal 10 sites. You can safely update without issues :)
