Fall 2023 package update

[budak7273]

I updated to the latest Node and Next.js versions and it now compiles pages in like 5 seconds instead inside the container.

Looks like slow compilation has been an issue they are actively working on fixing: https://github.com/vercel/next.js/issues/48748

• Depends on #233 being merged first
• Updated frontend to Node 20.6.0
• Update NextJs to v13 following these docs: https://nextjs.org/docs/app/building-your-application/upgrading/app-router-migration#upgrading
• Update some frontend dependencies - it is probably possible to update them further if you want
• Updated CI node version matrix to 20.x
• Update docs to talk about how to upgrade major node versions

I tested by running the addNums.py experiment and everything behaved as expected.

If you get:

panic: runtime error: index out of range [3] with length 3

goroutine 1 [running]:
main.checkVersionExceedsLatest({0x11c0e0d0, 0x6})

running the dev install script, you should update to the latest NVM: https://github.com/coreybutler/nvm-windows/releases/download/1.1.11/nvm-setup.exe
