fix(stepfunctions-tasks): sageMakerCreateTrainingJob does not correctly support empty inputDataConfig

[xazhao]

Issue # (if applicable)

Closes #31132.

Reason for this change

inputDataConfig is not a required property in the API: https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_CreateTrainingJob.html#sagemaker-CreateTrainingJob-request-InputDataConfig

However in SageMakerCreateTrainingJob, it's marked as required. We should make it align with the API.

Description of changes

Make the property optional.

Description of how you validated changes

unit test and integration test
