Reference: https://docs.aws.amazon.com/Route53/latest/APIReference/API_DisassociateVPCFromHostedZone.html#API_DisassociateVPCFromHostedZone_Errors

This is a best effort fix for the errors returned by the Route 53 `DisassociateVPCFromHostedZone` API, which are unrelated to the potential errors during the `Read` function that uses the `ListHostedZonesByVPC` API. The acceptance testing framework does not lend itself well to testing this situation and this highlights a case where #15945 would need special handling.
