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-davism5403/

打开 README 并检查仓库描述设置。将两个 URL 更新为 https://githubschool.github.io/github-games-davism5403/，然后验证 README 链接和仓库描述是否指向该地址。
