Don't deploy the site on GitHub pages

After spending way too much time getting GitHub Actions, Parklife, and
GitHub Pages to play well together, I've decided to just host the site
on our Hatchbox-managed server instead.

That took 5 minutes to get running and we even have the option, but
admittedly we're not yet running the static version.
