docs: <p>
  Removes authorization to submit an <code>AssociateVPCWithHostedZone</code> request to associate a specified VPC
  with a hosted zone that was created by a different account. You must use the account that created the hosted zone
  to submit a <code>DeleteVPCAssociationAuthorization</code> request.
  </p>
  <important>
  <p>
  Sending this request only prevents the AWS account that created the VPC from associating the VPC with the Amazon
  Route 53 hosted zone in the future. If the VPC is already associated with the hosted zone,
  <code>DeleteVPCAssociationAuthorization</code> won't disassociate the VPC from the hosted zone. If you want to
  delete an existing association, use <code>DisassociateVPCFromHostedZone</code>.
