Add a documentation site

[endormi]

I think it's better to have a documentation site instead of just a markdown file.

If this is something you want, I can start working on it.

Hi @endormi 👋

What a nice idea ❤️ Would you mind sharing here some mockups before doing it?

[endormi]

Yeah, I absolutely can share mockups before doing it @frinyvonnick 😃

I'm using docsify.

Awesome 👍 You can create a package gitmoji-changelog-documentation to put the code of the website.
