Game broken

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

打开仓库设置，检查 master 分支是否已启用 GitHub Pages。确认已发布的 URL 不再返回 404；inde.html 命名问题已单独列出，不是此处请求的更改。
