transfer : CopyStepDetailsProperty Wrong CloudFormation Mapping

[Zahra-97]

Describe the bug

AWS::Transfer::Workflow CopyStepDetails is generated with camel case. AWS API requires Properties in Pascal Case:

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-transfer-workflow-copystepdetails.html
{
"DestinationFileLocation" : S3FileLocation,
"Name" : String,
"OverwriteExisting" : String,
"SourceFileLocation" : String
}

Python code:

Expected Behavior

Json Template output with pascal case properties

Current Behavior

Json Template output with camel case properties.

Reproduction Steps

`

copy_step_details_property = transfer.CfnWorkflow.CopyStepDetailsProperty(
          destination_file_location=transfer.CfnWorkflow.S3FileLocationProperty(
              s3_file_location=transfer.CfnWorkflow.S3InputFileLocationProperty(
                  bucket=bucket.bucket_name,
                  key="csv"
              )
          ),
          name=cp_to_s3,
          overwrite_existing="TRUE",
          source_file_location="${original.file}"
      )
    
cfn_workflow = transfer.CfnWorkflow(
    self,
    "CopyToS3",
    steps=[
        transfer.CfnWorkflow.WorkflowStepProperty(
            copy_step_details=copy_step_details_property
            )
    ],
    description='copy_to_s3'
    
)

All the properties are loosely typed as Any. You will need to define JSON for that.

e.g.

copy_step_details_property = {
  "DestinationFileLocation" : S3FileLocation,
  "Name" : String,
  "OverwriteExisting" : String,
  "SourceFileLocation" : String
}
