Electric Clojure demo has no link back to GitHub

This URL: https://electric.hyperfiddle.net/

Has no link to this URL: https://github.com/hyperfiddle/electric

So when I send people to the former, so they can see how it's the Raptor 3 of frontend/backend frameworks, they can't easily find GitHub.

Please fix.
