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-pgaduputi/

更新 README 和仓库描述中的 URL，这两者目前都指向 githubschool 的副本。将它们替换为 https://githubschool.github.io/github-games-pgaduputi/，并验证两个链接都指向仓库中的游戏副本。
