Update package for Django v4.2 compatibility

[mikkonie]

As I started working on bihealth/sodar-core#880, I also have to our update other related packages to work with Django v4.2+. Issues detected will be listed below.

Issues

• Replace django.utils.translation.ugettext_lazy imports with gettext_lazy
• Fix providing_args arg for Signal() (1)
• Replace django.conf.urls.url imports with django.urls.re_path

Cleanup

• Ensure changes are backwards compatible to v3.0 where possible
• Update versions in CI
• Update readme
