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-austin2152/

檢查 repository 描述和 README，找出現有的兩個遊戲連結，然後將它們與 issue 的目標 URL 進行比較。更新這兩個參照，使其指向 repository 的 GitHub Pages 副本，並確認每個連結都能正確解析。
