a number of syntax is no longer available in Sagemaker >=2

[QuanNguyenAUT]

Hi there,

After go around with this repo, it seems that some syntax is not sync to the Sagemaker ver >=2.

predictor = model.deploy(initial_instance_count, instance_type)
update_endpoint is a no-op in sagemaker>=2.
See: https://sagemaker.readthedocs.io/en/stable/v2.html for details.

sagemaker.Session().delete_endpoint(predictor.endpoint)
The endpoint attribute has been renamed in sagemaker>=2.
See: https://sagemaker.readthedocs.io/en/stable/v2.html for details.

Could you have a look and update the latest version?

Thank you so much.
