Game broken

When attempting to access this at https://githubschool.github.io/github-games-2031077/, 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 @2031077?

首先按照第一条中的要求，检查 GitHub Pages 的仓库设置以及它是否已在 master 上启用。验证已部署的 URL 不再返回 404；issue 还提到 index.html 被错误地命名为 inde.html，但这不在所请求的 fix 范围内。
