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-talktopiyush

打开 repository 描述和 README，然后找到指向 githubschool 游戏副本的两个链接。将两者都替换为 https://githubschool.github.io/github-games-talktopiyush，并验证描述和 README 现在显示的是 repository 副本的 URL。
