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-lfrey-gss/

打开 README 和仓库设置，然后检查当前用于游戏链接的两个 URL。将每个 URL 更新为指向 https://githubschool.github.io/github-games-lfrey-gss/，并验证 README 链接和仓库描述现在显示的是预期目标。
