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-vipulgaur99/

打开 repository 描述和 README，并检查这两个位置中现有的游戏 URL。将每个不正确的链接替换为 https://githubschool.github.io/github-games-vipulgaur99/，并验证这两个链接都指向 repository 中的游戏副本。
