Game broken

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

- GitHub pages needs to be enabled on main. 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 @hdewees?

先检查仓库的 GitHub Pages 设置，然后检查 issue 中指定的根入口文件 index.html。确认与课程关联的 Pages URL 能够成功加载，而不是返回 404；当该 URL 可以访问时，issue 请求的工作就完成了。
