Update Tailwind config so jit-refresh.css is git ignored

[jaredcwhite]

Resolves #547

To set it up in an existing project, just make sure you've added frontend/styles/jit-refresh.css to your .gitignore file (you might have to delete it and commit first). Then update your Rakefile so it has the line

sh "touch frontend/styles/jit-refresh.css"

right at the top of both the :build task and the :dev task. For example:

namespace :frontend do
  desc "Build the frontend with esbuild for deployment"
  task :build do
    sh "touch frontend/styles/jit-refresh.css"
    sh "yarn run esbuild"
  end

  desc "Watch the frontend with esbuild during development"
  task :dev do
    sh "touch frontend/styles/jit-refresh.css"
    sh "yarn run esbuild-dev"
  rescue Interrupt
  end
end
