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-mkazhamiaka

检查 repository 描述和 README，找到 issue 中提到的两个链接。将两个 URL 更新为 https://githubschool.github.io/github-games-mkazhamiaka，然后验证描述和 README 是否指向 repository 中的游戏副本。
