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-Bonni

先檢查 README 和儲存庫描述，也就是 issue 中提到的兩個位置。將兩個 URL 更新為指定的儲存庫位址，然後確認每個連結都指向該儲存庫自己的遊戲副本。
