Upgrade flake8-django to support astroid to >=3.0, to prevent pylint downgrades

[rxm7706]

Installing flake8-django downgrades pylint - because flake8-django is restricted to astroid = "^2.15.2"

pylint (>=3.0.2,<4.0.0) requires astroid (>=3.0.1,<=3.1.0-dev0)

I believe that this restriction could also prevent python 3.12. Astroid added support in v3.0.0

EDIT: whoops. Yes. And that is already mentioned in https://github.com/rocioar/flake8-django/pull/134
