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-jaw395/

更新 github-games-jaw395 的仓库描述和 README 中的 URL。将这两个位置与 https://githubschool.github.io/github-games-jaw395/ 进行比较，并在完成后确认它们指向该副本。
