Create Snippets for `aws_sagemaker`

[sameeramin]

We need to create code snippets for AWS SageMaker resources in our VSCode extension. SageMaker is a fully managed machine learning service that enables developers to build, train, and deploy machine learning models at scale. The snippets should cover common SageMaker resources and configurations, such as creating training jobs, defining model endpoints, and configuring hyperparameters.

Tasks:

• Create code snippets for common AWS SageMaker resources and configurations.
• Ensure the snippets cover a range of use cases and configurations commonly used with SageMaker.
