Add names of contributors to each page

In the spirit of the docs being open-source I think it would be a nice feature to add an automatically generated footnote to each docs page with the usernames and a word of thanks to the people that contributed to that particular page. Not anything too big, but just a small note at the bottom of the page would suffice

I don't think we need such a big "thankyou" title, I think this can just be a couple of lines and text with no header

Here are the updated designs without a header
