404 "Getting Started" link on landing page

[Madoshakalaka]

This is about:

• Outdated documentation

Problem

https://yew.rs has a Getting Started 404 link.

It's partly caused by docusaurus v2 update... the demo site built with v1 also had this issue when the version was set to next.

But currently, the link just doesn't work at all, on either 0.18, 0.19, or next.

Additional context (Optional)

I did some research and couldn't figure out how to reference the getting started introduction on the index page. Maybe we should remove it.

docusaurus' own page does this pretty well - they have a Get Started button on the index page too. And it works as expected whichever version is choosed.
I believe it's only possible when the index is written in react
See how they are doing it:
https://github.com/facebook/docusaurus/blob/main/website/src/pages/index.tsx#L114-L116

That said...our current index is already MDX, it should allow react code?

#2226 should fix it.

We need better slugs and home page. A little documentation introduction will be under /docs so we can link to it (like docusaurus' site does)
