    .SYNOPSIS
        Amazon Cognito user pool has self registration disabled

    .DESCRIPTION
        **Amazon Cognito user pools** are evaluated for **self-service sign-up**. The expected configuration is `AllowAdminCreateUserOnly=true` so only administrators create accounts.
        
        *When self sign-up is allowed*, the check also highlights any linked identity pools and the authenticated role(s) that new users could assume.

    .PARAMETER Check
        CIEMCheck object containing check metadata.
