URL in description and README broken

The URL in the repository description and 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-deepdhan/

Open the README and repository description, then update the game URL in both locations to point to this repository's copy. Verify that each link targets the github-games-deepdhan page and that the README still renders correctly.
