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-jguzman80/

检查仓库描述和 README，然后将两个 URL 与 issue 中给出的目标 URL 进行比较。更新这两个引用，使其指向完全相同的游戏地址，并验证两个链接都解析到此仓库的副本。
