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-kdingh

Open the README and the repository settings, then locate the two existing game URLs. Update both references to https://githubschool.github.io/github-games-kdingh and verify that the README link and repository description point to that destination.
