URL in description and README broken

The URL in the repository description and the one in the 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-wa001sp

更新仓库描述和 README 中的 URL，将 https://githubschool.github.io/github-games-wa001sp 用作目标。确认这两个位置现在都指向此仓库中的游戏副本。
