Describe the feature or problem you’d like to solve

gh-repo-clone will clone repos, but not the wiki repo associated with it. For example, if this repo had a wiki, then gh repo clone cli/cli works, and git clone https://github.com/cli/cli.wiki.git works, but gh repo clone cli/cli.wiki will give the error GraphQL error: Could not resolve to a Repository with the name 'cli/cli.wiki'.

Proposed solution

Add the ability for Github CLI and/or GraphQL to find the wiki repositories.

Additional context

Add any other context like screenshots or mockups are helpful, if applicable.
