Update Development link to lead directly to GitHub

[JJRcop]

I propose the Development link on the website should lead directly to the GitHub

Pros:

• One less redirect, direct link
• User doesn't need to touch HTTP

Cons:

• ❗ If the source repository moves, the website must be updated, rather than transparently updating the URL forwarding service

See #149 (comment)

Thanks! In that case, I choose to leave the PR open for if they change their mind, or decide to close it.
