Game broken

When attempting to access this at https://githubschool.github.io/github-games-ramvee321, 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 @ramvee321?

从仓库设置开始，检查是否已启用 GitHub Pages，并将 master 分支作为其源，这正是第一条要求的内容。然后打开列出的 GitHub Pages URL，验证其是否能够加载；issue 还提到，如果 404 仍然存在，应检查文件名是否为 index.html，而不是 inde.html。
