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-nereus1/

打开 README 并检查仓库描述，然后将两个 URL 与 issue 中的目标 URL 进行比较。更新这两个引用，使其指向仓库的 GitHub Pages 游戏 URL，并验证 README 链接和描述链接能够正确解析。
