URL in description and README broken

The URL in the repository description and 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-gjogjo/

打开 repository 的 README 和其 GitHub 描述，检查当前的游戏 URL。将这两处引用都更新为 https://githubschool.github.io/github-games-gjogjo/，并验证每个链接都指向该 repository 自有的游戏副本。
