Missing support for Endpoint for resource AWS::RedshiftServerless::Workgroup

### Name of the resource

Other

### Resource name

AWS::RedshiftServerless::Workgroup

### Description

When constructing a resource of type `AWS::RedshiftServerless::Workgroup` ([link](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-redshiftserverless-workgroup.html) to docs) it does not seems to be way to associate it with a (Redshift Serverless managed VPC) endpoint.

The endpoint property ([link](url) to docs) seems to be unrelated to the Cloudformation `AWS::RedshiftServerless::Workgroup` resource.

Is there support from Cloudformation to create such VpcEndpoint?

### Other Details

The [corresponding API](https://docs.aws.amazon.com/redshift-serverless/latest/APIReference/API_CreateEndpointAccess.html) call works properly

Start with the AWS CloudFormation documentation for AWS::RedshiftServerless::Workgroup and the linked CreateEndpointAccess API reference. Determine whether CloudFormation can associate this resource with a Redshift Serverless managed VPC endpoint; done means the requested endpoint association is supported or the limitation is clearly documented.
