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-Ping-LAC/

檢查儲存庫描述和 README，著重查看各處的遊戲 URL。將兩個參照都更新為 https://githubschool.github.io/github-games-Ping-LAC/，並確認描述和 README 現在都指向該目的地。
