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-vbasvabovina/

更新 issue 中提到的 repository 描述和 README。检查每个当前 URL 并将其更改为 https://githubschool.github.io/github-games-vbasvabovina/，然后验证两个链接都指向 repository 中的游戏副本。
