Update www.vikkiez CNAME after Netlify project rename

My Netlify project was originally named "vikikiez-portfolio" 
(typo), which gave it the default subdomain 
vikikiez-portfolio.netlify.app. I've since renamed the project 
to "vikkiez", which changed its Netlify subdomain to 
vikkiez.netlify.app.

This PR updates the CNAME record in www.vikkiez.json to point to the new address so that www.vikkiez.is-a.dev continues to resolve correctly. The root domain (vikkiez.json, using an A record) is unaffected by this change.
