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-TimothyMayfield

檢查 repository 描述和 README 中現有的兩個遊戲 URL。將兩者都更新為 https://githubschool.github.io/github-games-TimothyMayfield，然後確認描述中的連結和 README 連結是否解析到此 repository 的遊戲副本。
