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-arojas-lac/

Open the README and the repository description settings, then inspect both existing game links. Update each URL to the repository's GitHub Pages address shown in the issue and verify that both links resolve to the project's copy.
