Update URL API link and status

[rubys]

From production/app/static/ie-status.json:

 {
"name": "URL API",
"category": "DOM",
"link": "https://dvcs.w3.org/hg/url/raw-file/tip/Overview.html",
"summary": "Expose constructible URL objects that can be manipulated and combined.",
"standardStatus": "Established standard",

The link is no longer active (it redirects). Consider updating it. Candidates:

• https://url.spec.whatwg.org/
• https://specs.webplatform.org/url/webspecs/develop/
• http://www.w3.org/TR/url/

Additionally, the standardStatus is incorrect. I'd suggest "Editor's draft" instead.

I suggest using https://url.spec.whatwg.org/, as this is where the original link redirects to.
