Game broken

When attempting to access this at https://githubschool.github.io/github-games-davism5403/, 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 @davism5403?

打开仓库设置，检查是否已在 master branch 上启用 GitHub Pages，如第一条要求所述。然后重新访问 https://githubschool.github.io/github-games-davism5403/；当它不再返回 404 时，该 issue 就完成了。index.html 的命名问题已单独列出供课堂使用。
