Allow passing an --active flag to gh auth status #9434
Description
Right now, when you do gh auth status, it can output multiple accounts, only one of which is active:
% gh auth status
github.com
✓ Logged in to github.com account tjschuck (GITHUB_TOKEN)
- Active account: true
- Git operations protocol: https
- Token: ghp_************************************
- Token scopes: 'notifications', 'read:org', 'repo', 'workflow'
✓ Logged in to github.com account tjschuck (keyring)
- Active account: false
- Git operations protocol: https
- Token: gho_************************************
- Token scopes: 'gist', 'read:org', 'read:packages', 'repo', 'workflow'
Ideally, you'd be able to do something like gh auth status --active to get only the active account listing. This is useful if you want to, for example, check the current scopes available for the active token.
