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-JMA21

Open the repository description and README and inspect both game URLs. Update each link to https://githubschool.github.io/github-games-JMA21, then verify that both locations point to the repository's own game copy.
