Game broken

When attempting to access this at https://githubschool.github.io/github-games-JohnEHarris, I am getting a 404. This could be caused by a couple things:

- GitHub pages needs to be enabled on main. 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?

打开仓库设置，并按照第一个要点中的要求检查 main 分支的 GitHub Pages 配置。验证已发布的网站 https://githubschool.github.io/github-games-JohnEHarris 不再返回 404；单独的 index.html 命名问题不在此次请求范围内。
