Description
AlterableComposableSchema uses ContainerAwareEventDispatcher
Change log: https://www.drupal.org/node/3376090
Introduced: 10.3.0
Drupal\Component\EventDispatcher\ContainerAwareEventDispatcher is now deprecated. If you were extending this with your own dispatcher then you need to refactor to extend Symfony\Component\EventDispatcher\EventDispatcher instead.
