Game broken

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

首先检查 GitHub Pages 的仓库设置，以及是否按照第一条中的要求配置为从 master 发布。通过打开 https://githubschool.github.io/github-games-opaliivets 并确认其不再返回 404 来验证此更改。另行提到的 inde.html 问题不在本请求范围内。
