Add key bindings documentation to the web page

@saliaku maybe it helps if you read through the existing documentation (on source level). It's not much, we don't have much yet, so it shouldn't take long at all.

This should give you a good understanding on how to extend it.

On top of that, feel free to ask questions on Discord, in #contour-dev or #contour chat. :)
