Hotwire version 2!

[epugh]

Description

We want to get to the future of dynamic interactive website without lots of JS ;-).

Motivation and Context

Replaces the first version in #870 with a better approach that uses importmaps + sprockets instead of sprockets + esbuild based something or other. So this appears to let us keep the old build for the AngularJS but also adopt new Turbo stuff.
