[AWS::Grafana::Workspace] - [BUG] - ClientToken without apparent purpose in CloudFormation context

### Name of the resource

AWS::Grafana::Workspace

### Resource Name

AWS::Grafana::Workspace

### Issue Description

The [resource parameters ](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/aws-resource-grafana-workspace.html) include ClientToken with the description `A unique, case-sensitive, user-provided identifier to ensure the idempotency of the request.`

I think this does not make sense in the CloudFormation context and is just a copied over remnant from the [CreateWorkspace API](https://docs.aws.amazon.com/grafana/latest/APIReference/API_CreateWorkspace.html). For the API it makes sense to be idempotent, but not for the deployment model of Cloudformation.
If it serves no purpose, it should be removed.

### Expected Behavior

ClientToken having a purpose or not be a parameter.

### Observed Behavior

ClientToken being a parameter without apparent purpose.

### Test Cases

documented resource parameters

### Other Details

_No response_

Start by comparing the AWS::Grafana::Workspace resource parameters with the linked CreateWorkspace API documentation, focusing on ClientToken and CloudFormation behavior. Confirm whether ClientToken has a CloudFormation-specific purpose; done means its purpose is documented or the parameter is removed from the resource documentation.
