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-BinduTuli0609

更新 repository 描述和 README，它们当前指向 githubschool 的游戏副本。将两个 URL 都改为 https://githubschool.github.io/github-games-BinduTuli0609，然后检查渲染后的 repository 页面和 README，确认两个链接都正确。
