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-jugalera/

Update the repository description and README, which are the two locations named in the issue. Verify that both URLs point to https://githubschool.github.io/github-games-jugalera/; the work is done when neither location links to githubschool's copy.
