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-rd-boris-mechkov/

Inspect the repository description and README, the two locations named in the issue, and compare their current game URLs with the target URL provided. Update both references so they point to https://githubschool.github.io/github-games-rd-boris-mechkov/; done means neither location points to githubschool's copy.
