bug: namespace "form_builder" not registrated

[maxnoelp2]

Describe the bug
I installed form_builder and try to use it, but i got this error "Exception when rendering template in FormPlugin (id=4673)
NoReverseMatch: 'form_builder' is not a registered namespace".
Now i Added path("forms/", include("djangocms_form_builder.urls", namespace="form_builder")), in my urls.py and it works.

Its the second time for the same error, in the first error it works without i must do anything, but now i must add in my urls.py to fix it.

@maxnoelp2 It is perfectly ok to add form builder's end point directly to your URLs. One might argue this is the best thing to do, since you have full control over the URLs.

If form builder is not registered with Django's URLs, djangocms_form_builder.apps will register it after initializing. This is a minimal way of auto-configuration.

I am not sure, I understand exactly when the issue appears. Are you missing the auto-config for the URLs?
