Chinese version of the website
This is the initial request to add Chinese. I set up everything and took care of the technical part, translations are made by @XMRNoblesse.
The only translated file at the moment is
zh-cn.yml. We will work together to add at least footer and navigation. I will remove WIP after at least one review of the complete translation.
This MR is based on !994 (merged) , which is needed to build correctly
