[RFC] Documentation Website

**Hi everybody!**

Hope your doing good, I’ve put together a proposal for the project’s docs website, you can give it a **try here: [website](https://graphql-go.github.io/graphql-go.org)** – And the **code here: [GitHub Repo](https://github.com/graphql-go/graphql-go.org)**

**Sharing a quick summary about the implementation:**
* Built on top of Docusaurus.
* Pages: Overview, Installation, Quick Start & Examples.
* Support for multiple versions.
* Light & Dark UI Themes.
* All pages can be edited via GitHub’s PR (Via: “Edit this page” link on each page).

Please share your **thoughts & feedback**, together we can make it better.

Thanks in advance!
