Fix documentation "Get Started" button

[Erik van den Brink]

The repo has a link to the documentation in the about section pointing here: https://dojo.coz.io/neo3/neon-js/index.html

That shows a page looking like this

Clicking the "Get Started" button on the above page should show this

but instead goes here

Note how the url in the address bar is the same but the content is not.
Pressing "Neon-js" there gets you back to the first screenshot. It goes around in an endless loop.
