## Is your feature request related to a problem? Please describe.

WingetUI is an excellent self-serve utility for organizations with internal repositories. It would be great if WingetUI could honor repos flagged for admin only and/or flagged for self-serve.

## Describe the solution you'd like

Like if user does not have admin privileges and admin only is set to true then don't show/check that repo. Or if self-serve is set to false and user is not admin don't permit installation (or prompt for elevation), etc. Repos default to false for both so probalby would need an override as well. which i suspect would need to be on by default.
