### Description

This feature adds support for Redshift Serverless clusters for the given operator.

### Use case/motivation

RedshiftDataOperator currently only supports provisioned clusters since it has the capability of adding `ClusterIdentifier` as a parameter but not `WorkgroupName`. The addition of this feature would help users to use this operator for their serverless cluster as well.
