Update: We are going to use the same PR we have open for the feedback widget

The feedback widget will have a link to this contributing landing page. It will also live in the side bar in docs. Open to hearing if anyone feels it should live somewhere else

At the bottom of the page we are also going to reuse the 'join the community' component that we have in the docs/index page.
This should be ready to preview by tomorrow morning.

Update: we'll leave the 'thank you' section out until we hear from Julie on potential liability. The hackmd is revised, and will live at open-source/contributing . Nick will do it by EOD
