netbox-plugin-dns: AttributeError: module 'netbox_dns' has no attribute 'config'

Versions NetBox Version: 3.6.4 NetBox DNS Version: 0.21.3 (latest) Python Version: 3.9.18

Describe the bug When I run the migrate script I get this error:

(venv) [root@netbox netbox]# ./manage.py migrate
Traceback (most recent call last):
  File "/opt/netbox-3.6.4/netbox/netbox/settings.py", line 749, in <module>
    plugin_config: PluginConfig = plugin.config
AttributeError: module 'netbox_dns' has no attribute 'config'

During handling of the above exception, another exception occurred:

    raise ImproperlyConfigured(
django.core.exceptions.ImproperlyConfigured: Plugin netbox_dns does not provide a 'config' variable. This should be defined in the plugin's __init__.py file and point to the PluginConfig subclass.

To Reproduce Follow installation procedure.

Expected result Expect it to work.

Actual result Netbox doesn’t load unless I remove the plugin from the list
