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-Mike-the-powerful

Update the URL in the README and the repository description. Check both locations against https://githubschool.github.io/github-games-Mike-the-powerful, then verify that neither still points to githubschool's copy and that both links resolve to the intended game.
