Effortlessly install TailwindCss in a Rails app with Webpack (minimum configuration)

A while back DHH decided to created a gem for easily installing TailwindCss into rails apps 🙌🏻. This gem could be used to install Tailwind through the asset pipeline as well as using webpack. This changed later on as contributors wanted to focus their attention to what was the heart of the gem 🥺.

Well, since a lot of people used this gem to get a new Rails app going with Tailwind without the hassle of configuring everything from scratch (including colleagues from my company), we decided to create a new gem 🎉. This gem installs Tailwind with Webpack and has production purging enabled. Other Webpack specific problems are to be addressed as well.
