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-TomFoxall/

開啟儲存庫描述和 README，找出指向 githubschool 遊戲副本的兩個連結。將兩者都更新為 https://githubschool.github.io/github-games-TomFoxall/，並確認每個連結都能解析到儲存庫的副本。
