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-Jerdakos

Update the repository description and README mentioned in the issue. Replace both incorrect URLs with https://githubschool.github.io/github-games-Jerdakos, then verify that the description and README link to the repository's copy of the game.
