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-jasonkangas

打开 README 并检查仓库描述设置。将两个 URL 都更新为指向 https://githubschool.github.io/github-games-jasonkangas，然后验证显示的链接是否解析到仓库中的游戏副本。
