Fix Deprecated IP

[mzagaja]

codeforboston.org is improperly configured
The custom domain for your GitHub Pages site is pointed at an outdated IP address. You must update your site's DNS records if you'd like it to be available via your custom domain. For more information, see Learn more (DeprecatedIPError). We recommend you add an A record pointed to our IP addresses, or an ALIAS record pointing to codeforboston.github.io.
