Add Tailwind

[colegoldsmith]

This work adds some tailwind css and a config file. The config file is included in the UI bundle.

On the antora site just after building we can run this script to bake all the tailwind css into site.css

tailwindcss build -c ./build/site/_/js/tailwind.config.js -i ./build/site/_/css/site.css -o ./build/site/_/css/site.css --minify

This way the tailwind config and tailwind css additions live in the UI bundle repo, and are passed to the site repo to be used once all the html is generated
