Updates domain configurations and adds new subdomains

Modifies existing domain records:
- Updates TXT record in '_vercel.mzaman.json'
- Changes CNAME target in 'mzaman.json' to point to the new version of the portfolio

Adds new subdomain configurations:
- Introduces '_vercel.www.mzaman.json' for Vercel DNS with CNAME and TXT records
- Adds 'www.mzaman.json' to point to the new portfolio version

Ensures proper routing and verification for the updated and new subdomains.
