The instructions for this project need to be updated to use another CDN in front of GitHub. From the RawGit web site:
October 8, 2018
RawGit is now in a sunset phase and will soon shut down. It's been a fun five years, but all things must end.
GitHub repositories that served content through RawGit within the last month will continue to be served until at least October of 2019. URLs for other repositories are no longer being served.
If you're currently using RawGit, please stop using it as soon as you can.
Of the choices suggested on the RawGir page, jsDelivr seems to work for this purpose. It has a migration applet that can help update references to use jsDelivr URLs instead of RawGit.
