Config import fails when importing multiple entity_type_behaviors

I'm not sure if one should use the same sandbox parameter for all entity types. Using a different sandbox parameter seems to fix the issue: https://git.drupalcode.org/issue/entity_type_behaviors-3387281/-/commit/...

Sorry it seems the issue was caused by a config for an entity type that does not have bundles. Which is not supported - or is it?

I could reproduce this issue in a vainlla D10 setup, activating entity_type_behaviors for nodes and terms and importing them at the same time in an other environment via drush config-import.

Your patch seems to solve this issue. Of course it would be nice to have some kind of UI integration for entity_types without bundles, but the default issue here is kinda critical and makes this module unusable.

Alright, the patch looked good to me. I added some tests to make sure it won't fail again.
Since there are no tests activated on the project, we don't see anything :( But I could reproduce the described error message with the test, and the commit from @Harlor did indeed fix it.

Maybe @Harlor Could give me a quick review on the test before setting this to RTBC.

LGTM

Merged to 2.0.x. Thanks!
