Lambda cannot be updated in the SageMaker Pipelines LambdaStep

[xietao0221]

Describe the bug
I am able to use LambdaStep to create a Lambda function that is used by SageMaker Pipelines when the Lambda does not exist. But after I update the Lambda script, I expect the Lambda function would be updated but it is not.

To reproduce

1. execute the sagemaker pipeline, that includes a lambda step, the first time to create the lambda function
2. update the lambda script
3. run the sagemaker pipeline again, the lambda script won't be updated to reflect the change

Expected behavior
The lambda script will be updated to reflect the change defined in the sagemaker pipeline

Screenshots or logs
