URL in description and README broken

The URL in the repository description and README are pointing to githubschool's copy of the game instead of yours.

Please fix both so they point to your copy of the game at https://githubschool.github.io/github-games-cwickett-gss/

首先打开仓库的 README，并检查 GitHub 设置中的仓库描述。更新这两个链接，使其指向 https://githubschool.github.io/github-games-cwickett-gss/，然后验证每个链接都解析到这个游戏的副本。
