Remove unnecessary WWW prefix in various URLs and update CBL link

Some websites redirect to www. like Adelie. I'd prefer if we used the target links (after redirection) directly to prevent further redirections.

@AlbydST While you're at it, why not also check for dead links? and maybe create a section for dead projects. I've been thinking of improving this list a bit by categorizing it a bit, and maybe adding more information.

Let me know what you think!

Good idea, I'll see what I can do
