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-jheavin-iit

Start by opening the repository settings to inspect the description, then read the README to locate its game URL. Update both references so they point to the repository's GitHub Pages game URL, and verify that the description and README contain the same destination.
