[@aws-cdk/aws-stepfunctions-tasks] SageMakerCreateTrainingJob fails on deploy The field "AtttributeNames" is not supported by Step Functions

[mirgj]

As per title trying to deploy a step function with SageMakerCreateTrainingJob will fail due to a typo in the code. AtttributeNames should be replaced with AttributeNames

aws-cdk/packages/@aws-cdk/aws-stepfunctions-tasks/lib/sagemaker/create-training-job.ts

Line 256 in 75e6d25

...(channel.dataSource.s3DataSource.attributeNames ? { AtttributeNames: channel.dataSource.s3DataSource.attributeNames } : {}),

Reproduction Steps

Just create a SageMakerCreateTrainingJob with a inputDataConfig field. eg

inputDataConfig: [
  {
    channelName: 'train',
    inputMode: tasks.InputMode.PIPE,
    contentType: 'application/x-recordio',
    recordWrapperType: tasks.RecordWrapperType.RECORD_IO,
    dataSource: {
      s3DataSource: {
        attributeNames: ['source-ref', 'class'],
        s3DataType: tasks.S3DataType.AUGMENTED_MANIFEST_FILE,
        s3Location: '...'
      },
    },
  },
  {
    channelName: 'validation',
    inputMode: tasks.InputMode.PIPE,
    contentType: 'application/x-recordio',
    recordWrapperType: tasks.RecordWrapperType.RECORD_IO,
    dataSource: {
      s3DataSource: {
        attributeNames: ['source-ref', 'class'],
        s3DataType: tasks.S3DataType.AUGMENTED_MANIFEST_FILE,
        s3Location: '...'
      },
    },
  },
],
