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-Phil25200

更新 github-games-Phil25200 的仓库描述和 README 中的 URL。确保两者都指向 https://githubschool.github.io/github-games-Phil25200，然后验证显示的链接不再指向 githubschool 的副本。
