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-Gymky

Start by checking the repository description and README for the two existing game URLs. Update both to https://githubschool.github.io/github-games-Gymky, then verify that the description and README each point to the repository's own game copy.
