Fix django_tailwind

I was missing package.json in git due to a too liberal .gitignore conf.
This botched tailwind when I restarted from a fresh git install

I never ran into this before b/c tailwind's npm stuff is only necessary during
development, not in e.g. localbugsink (because we checkin all outputs too)
