[Docs] expand docs to discuss Tailwind integration when using Vite with React

[pdevito3]

Is your feature request related to a problem? Please describe

Describe the solution you'd like
Similar to #14929, given tailwind css being the most popular css framework of 2019 and 2020, it would be highly appreciated if you could expand the docs to go into how you can add tailwind to a project using react and Vite with storybook.

I personally have a newer project with postcss 8+, but having content go over both <=7 and 8+ would be useful.

Describe alternatives you've considered
I've tried using all the next builds as well as the postcss plugin, but could be missing something with the syntax.

Are you able to assist to bring the feature to reality?
I'm happy to try it out and confirm working builds, but I don't have enough depth in this domain to have a meaningful contribution.

Closing this for now--please let me know if you think this ISN'T Vite-related and I'll reopen. Thank you! 🙏
