Game broken

When attempting to access this at https://githubschool.github.io/github-games-jbs5619/, 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 @jbs5619?

首先检查 repository 的 GitHub Pages 设置以及 https://githubschool.github.io/github-games-jbs5619/ 的部署目标。确认该站点是否配置为从 master 发布，然后验证该 URL 是否能够加载，而不是返回 404。如果检查设置无法解决问题，issue 还提到了 index.html 和 inde.html。
