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-Savita-dev/

檢查 repository 描述和 README 中是否有指向 githubschool 遊戲副本的連結。將兩個 URL 更新為 https://githubschool.github.io/github-games-Savita-dev/，並驗證描述和 README 現在是否指向該副本。
