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-alinder2/

開啟 README 和儲存庫設定，然後將現有的兩個連結與要求的目的地進行比較。更新 README URL 和儲存庫描述，使兩者都指向 https://githubschool.github.io/github-games-alinder2/，並確認每個連結都能解析到這個遊戲副本。
