[📑 Docs]: Lets create a welcome page for the docs section

[benjagm]

What Docs changes are you proposing?

Inspired by the good work of AsyncAPI Team, we think it would be great to create a welcome page to our docs section with a welcome message and a card for each subsection of our docs:

• Overview
• Getting started
• Reference
• Specification

This will also required add a new section on top of the sidebar called Welcome. We'll need to make this totally consisten with the style of our website.

See images for inspiration:
