Django 4.0 Support

[Oisota]

I ran into import errors when upgrading a project to Django 4.0. This line specifically:

djangocms-forms/djangocms_forms/apps.py

Line 6 in eaa6415

from django.utils.translation import ugettext_lazy as _

This function has been removed in the latest version of Django. Is Django 4.0 support being worked on? If not, I'd be happy to work on it and submit a PR.

I haven't done any Django 4.x work on this yet. I originally assumed we would need to wait for CMS 4.0 for Django 4 support, but it looks like it's in 3.11.

I've only just started moving projects up.

The short fix for that import is

from django.utils.translation import gettext_lazy as _

But, I assume there will be other updates that need to be made.

If you want to submit a PR, it will be gladly accepted.

I took some time tonight to make sure everything imports from the right place.
