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-wjohnsonbhs

更新 repository 描述和 README 中的 URL，使兩者都指向 https://githubschool.github.io/github-games-wjohnsonbhs。確認 README 連結和 repository 描述不再指向 githubschool 的副本，並且兩者都指向指定的遊戲 URL。
