Game broken

When attempting to access this at https://githubschool.github.io/github-games-robertscherbarth/, I am getting a 404. This could be caused by a couple things:

- GitHub pages needs to be enabled on master. You can fix this in the repository settings.
- the index.html file is incorrectly named inde.html. We will fix this together in class.

Can you please fix the first bullet @robertscherbarth?

Start in the repository settings and inspect the GitHub Pages configuration for the master branch, then verify the published URL no longer returns a 404. The issue also mentions index.html being incorrectly named inde.html, but the requested change is the Pages setting.
