Game broken

When attempting to access this at https://githubschool.github.io/github-games-jjengler, 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 @jjengler?

从仓库设置开始，检查 master 的 GitHub Pages 源配置；该 issue 明确要求修复第一条。确认 https://githubschool.github.io/github-games-jjengler 可以加载，而不是返回 404。
