Remove `create-react-app` option, Add new option 1 using Next.js?

[karlhorky]

Description

Now that create-react-app is going away (it's turning into a launcher), I would propose the following changes:

1. Remove all mentions of create-react-app from the tutorial (this is Option 1, so very visible)
2. Add a new Option 1 that uses Next.js instead - ideally using the App Router + React Server Components

Proposal

By changing the documentation and providing a polished, tested template using Next.js

@karlhorky This is a good idea. I think the quickest way to boot strap a new Spectacle deck when wanting to use JSX + React components is Vite, but Next App Router is also a good choice.

Thanks for this @carloskelly13 ! 🙌 @ProchaLu will try out migrating our slides from mdx-deck to Spectacle + Next.js + App Router.

Yeah! Let us know if you find anything during the migration!
