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-arch02

检查 repository 描述和 README，找到现有的两个游戏 URL。将两个链接都替换为 https://githubschool.github.io/github-games-arch02，然后确认 README 和描述显示的是已更正的目标地址。
