Upgrade possible

[mledwards]

This repo is great, thank you.

Not sure if this helps anyone but I upgraded next, storybook, autoprefixer, postcss, tailwindcss to the latest versions as off april 2022 (all with --legacy-deps), and removed @tailwindcss/postcss7-compat, and it worked first time 👍

New package.json

"dependencies": {
    "next": "^12.1.5",
    "react": "17.0.1",
    "react-dom": "17.0.1"
  },
  "devDependencies": {
    "@babel/core": "^7.13.8",
    "@storybook/addon-actions": "^6.4.22",
    "@storybook/addon-essentials": "^6.4.22",
    "@storybook/addon-links": "^6.4.22",
    "@storybook/react": "^6.4.22",
    "autoprefixer": "^10.4.5",
    "babel-loader": "^8.2.2",
    "postcss": "^8.4.12",
    "tailwindcss": "^3.0.24"
  }

I'm not currently able to do a PR, as this was all in amongst a project I'm halfway through, but I will when I get a moment.
