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-krutin86

从仓库描述和 README 开始，其中标识了失效的游戏 URL。将两处引用都更新为 https://githubschool.github.io/github-games-krutin86，然后验证每个链接都指向此仓库的游戏。
