**Describe the bug**
A clear and concise description of what the bug is.

This notebook was pruned as part of PR #4254
https://github.com/aws/amazon-sagemaker-examples/pull/4254/files#diff-097d09774d5fd4163417a25344450f281ba1220196e21812e67e29810c2d0efe

This example is referenced by a blog post https://aws.amazon.com/blogs/machine-learning/creating-a-machine-learning-powered-rest-api-with-amazon-api-gateway-mapping-templates-and-amazon-sagemaker/
which is now broken as a result of this pruning.

Can you restore this example please?

**To reproduce**
A clear, step-by-step set of instructions to reproduce the bug.

object2vec_movie_recommendation.ipynb is not available for users to select from the SageMaker notebook examples.

**Logs**
If applicable, add logs to help explain your problem.
You may also attach an `.ipynb` file to this issue if it includes relevant logs or output.

Start with introduction_to_amazon_algorithms/object2vec_movie_recommendation/object2vec_movie_recommendation.ipynb and compare its removal in PR #4254 with the linked blog post. Restore the example so users can select it from the SageMaker notebook examples and the published blog post no longer points to a missing example.
