Try using `gh` cli token as fallback when cloning github sources

[cpreston321]

Describe the feature

Github already provides this locally if you auth with gh in this case it can cover most private repo cases without creating a new token . This can used by trying to run it with execa fallbacks to undefined

E.g

options.auth = options.auth || (await execa('gh', ['auth', 'token']).then(r => r.stdout).catch(() => undefined))

Maybe it can be a CLI param like --use-gh-auth that enables this function to that might be more viable.
