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-git-for-shubh

打开 README，并检查 GitHub 仓库设置中的仓库描述。将两个过时的链接替换为指定的游戏 URL，然后验证 README 链接和描述是否解析到该仓库的副本。
