Check if DNS settings to www subdomain of biojs.io are still setup correctly

[jayjayjpg]

We had an issue on the biojs project page of links pointing to http://www.biojs.io not working anymore and which has been fixed in this PR by changing affected links to http://biojs.io instead. Still, in case that there are still links around on other BioJS sites pointing to the www subdomain of biojs.io or people using bookmarks pointing to it, it would be good to make http://www.biojs.io available again.

It would be good to check if the DNS settings for the www subdomain are still pointing to the correct website / bucket on AWS that is serving the registry ui.
