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-Anthonyjohnson5/

更新 repository 描述和 README 中的 URL，使两者都指向 https://githubschool.github.io/github-games-Anthonyjohnson5/。确认这两个位置都不再链接到 githubschool 的副本，并且显示的链接解析到这个游戏的副本。
