Updated dependencies

[lucasnad27]

I loved your Gatsby starter and followed through the instructions but immediately ran into dependency issues. I'm not familiar with most of these frontend tools (tailwind, framer, postcss, etc.,) but after reading through the docs, I was able to get it all working. I started with a fresh gatsby-starter-pack and then slowly added in the dependencies + gatsby plugins. I'd be happy to submit a PR with these changes if you're still interested in maintaining this starter pack. Some upgrade highlights...

"react": "^16.13.1", --> "^17.0.1",
"gatsby": "^2.21.0", --> "^3.13.0",
"tailwindcss": "^1.3.5" --> "^2.2.9",
"framer-motion": "^1.10.3" --> "^3.10.6",

I'll be building my own personal page now that I've got the starter working, but if you'd like to see any specifics of what I've done, here's a branch you can review.
