Replace archive link with actual link to the blog post (mdn#40505)

Ideally, archive links should be used only if the original URL/domain does not
work anymore, or has changed content that no longer matches the intent here.
That is not the case for this blog post, hence replacing the archive link with
actual URL feels like the right thing to do.

-An **IIFE** (Immediately Invoked Function Expression) is an idiom in which a {{glossary("JavaScript")}} {{glossary("function")}} runs as soon as it is defined. It is also known as a _self-executing anonymous function_.
