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-kanasanjeevan/

檢查 repository 描述和 README，其中顯示了兩個錯誤的遊戲 URL。將兩個 URL 更新為 https://githubschool.github.io/github-games-kanasanjeevan/，並驗證描述和 README 現在都指向該目標。
