Change group_content to group_relationship

I'm running group 3.3.5 in my environment and after installing Access Unpublished and Access Unpublished Group I was running into an error when accessing a node within a group with an access unpublished link. Changing group_content to group_relationship resolved the problem as group_content no longer exists in 3.x and I am now able to view the access unpublished page.

The error that I was receiving for full context:

Drupal\Component\Plugin\Exception\PluginNotFoundException:
The "group_content" entity type does not exist.
