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-mickeygousset

更新 repository 描述和 README 中的 URL，使兩者都指向 https://githubschool.github.io/github-games-mickeygousset，而不是 githubschool 的副本。先開啟 README 和 repository 設定，然後確認兩個連結都能解析到所述的遊戲 URL。
