Game broken

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

打开仓库设置并检查 GitHub Pages 配置，重点关注从 master 分支启用 Pages 的请求。随后检查已发布的 URL，并确认其是否能够加载；该 issue 还指出 index.html 和拼写错误的 inde.html 是相关的入口点。
