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-janusznowak/

Inspect the README and the repository description for the links that point to githubschool's copy. Update both to https://githubschool.github.io/github-games-janusznowak/ and verify that the README link and description URL resolve to the intended game.
