I updated this to be like the Clojure redirects, so that any navbar selection going to ONNX on a version that didn't exist will go to the API error page. I updated the [preview](http://34.201.8.176/) as well so you can test this out. Go to v1.0.0, then try to hit the Docs-->ONNX link in the nav. Once this passes CI, please merge.
