Make asciidoc.org live

This is a reporting issue to track what was done to make asciidoc.org go live. We were in a hurry to get it launched in time for the newsletter announcement, so we didn't have time to do this first.

• Sign into namecheap.com, where the asciidoc.org domain is currently registered
• Remove the existing A name records (which point to GitHub Pages)
• Remove the URL redirection record for the www subdomain
• Add an ALIAS record to point the site at Netlify ALIAS @ apex-loadbalancer.netlify.com
• Add a CNAME record to redirect the www subdomain (CNAME www asciidoc.netlify.app.)
• View the domain settings for the site in Netlify and verify the new DNS configuration
• Click the button to provision a new TLS/SSL certification via Let's Encrypt
• Update netlify.toml to redirect to mask the internal Netlify domain for the site
• Post the announcement of the relaunch to the asciidoc-wg list
