Game broken

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

首先检查 repository 的 Settings 中的 GitHub Pages 配置，并确认 Pages 已按照第一条的要求从 master 启用。确认已发布的 URL 不再返回 404；正文还指出 inde.html 是一个独立的索引文件问题，但此请求针对的是 Pages 设置。

由索引模型根据 Issue 内容生成。
