Game broken

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

打开仓库的设置，并检查 GitHub Pages 是否已启用，且以 master 作为发布源。重新加载 https://githubschool.github.io/github-games-ykim-bit/ 并确认它不再返回 404；issue 还提到了一个 inde.html 文件名，但要求先修复设置。
