Test in \Drupal\Tests\eca_config\Kernel\ConfigEventsTest::testConfigCrudEvents fails

The following test needs to be changed back to use [config:name] instead of [site:name] in https://git.drupalcode.org/project/eca/-/commit/24a274939e473c61d30989a1...

Method Drupal\eca\Token\DataProviderInterface::getData needs to return an instance of Drupal\eca\Plugin\DataType\DataTransferObject when it wants ECA to handle non-scalar values for token replacement.

Committed the points raised in #2 into !418. However this is not yet thoroughly tested, but hopefully helps for understanding.

Thanks a lot @mxh for fixing this, I had no time yet to look into it, but sure I broke that when migrating the eca_config module over to the new token provider structure.

Automatically closed - issue fixed for 2 weeks with no activity.
