Subject: [PATCH] Add hotwire-livereload

This is _optional_ and I would totally understand if we reject it
because we don't want to add another dependency.

But this PR would add livereload functionality to our Rails templates.
I've just tested it and it works almost instantly for CSS and JS
changes. This is a feature that we used to have for JS with Webpack but
lost with the new importmap setup. We've actually never had it for CSS,
so it's even fancier than before (yay!).

I thought it would be a nice thing to include since it could speed up
development for students during project weeks and also help with
teachers doing CSS changes in lectures.

I'm honestly not sure we need to explain this to students, but if we
wanted to, I could add it into our "front-end setup" guide, which is
done in some livecodes, or into the Rails Assets lecture. But I think
it's such a simple change (literally adding one gem and running a
Terminal command) that it's almost not worth the airtime.
