Just to drop the breadcrumbs: Given probing in #42, resulting in the deprecation: https://github.com/discoverygarden/embargo/actions/runs/10167131862/job/28118809195#step:4:1197

     1x: The Drupal\Tests\field\Traits\EntityReferenceTestTrait is deprecated in drupal:10.2.0 and is removed from drupal:11.0.0. Instead, use \Drupal\Tests\field\Traits\EntityReferenceFieldCreationTrait. See https://www.drupal.org/node/3401941
      1x in ClassLoader::loadClass from Composer\Autoload

I'm pretty sure tests should be fixed between:

• DDST-382: remove D10.1 from phpunit phpunit-action#22 and
• DDST-401: Use the renamed trait. islandora_test_support#7
