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-jonsun2008

Update the repository description and the URL in README so both point to https://githubschool.github.io/github-games-jonsun2008 instead of githubschool's copy. Start by opening the README and repository settings, then verify that both links resolve to the game's copy.
