Setup a static site for AIBrix project

[Jeffwan]

We need a static site for this project, it could be a separate website project (aibrix/website) using static site toolkit or built from some folders like docs from the same project. I personally prefer the docs folder. It's not a good idea to split the traffic into different repos at the beginning.

Since we have the site template now, we just need to add the content in future works. We can close this issue now.
