Admin ability to set global shared link settings by user type - such as no ability for a managed user to set a shared link to "anyone with the link" -- but admins and/or co-admins could set a shared link to be public (in the case of surfacing documentation externally). This could look like, under "Default access for shared links" setting in Admin Console, a new dropdown to allow for an override for co-admins or above, OR the ability to add specific users to an allowlist.
