BYO MME example notebook failing due to MXNet retirement

[brianloyal]

Link to the notebook https://github.com/aws/amazon-sagemaker-examples/blob/main/advanced_functionality/multi_model_bring_your_own/multi_model_endpoint_bring_your_own.ipynb

Describe the bug Running the first code cell in the "Upload model artifacts to S3" section produces an error that reads, "AssertionError: failed to open http://data.mxnet.io/models/imagenet/resnet/18-layers/resnet-18-0000.params". Browsing to https://mxnet.apache.org, I see that the project was retired in September 2023.

To reproduce Run the notebook in a SageMaker Notebook Instance
