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-thd-andres

打开 README 并检查仓库描述设置。将指向 githubschool 副本的链接替换为 https://githubschool.github.io/github-games-thd-andres，然后验证 README 链接和仓库描述都解析到此项目的游戏页面。
