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-waldreps

開啟儲存庫描述和 README，找出其中目前的遊戲 URL。將兩個連結都替換為 https://githubschool.github.io/github-games-waldreps，然後驗證儲存庫描述和 README 指向所要求的副本。
