[BUG] Federated Query with deployed ML Endpoint not working

[Kumfert]

Describe the bug See attached screenshot

To Reproduce Steps to reproduce the behavior:

1. Deploy from the website (I used us-east-1)
2. Open the Neptune-ML-03-Intro-to-Link-Predection-SPARQL notebook.
3. Patch the utility file notebooks/04-Machine-Learning/Neptune-ML-SPARQL/neptune_ml_sparql_utils.py (at least till next release)
4. Run all the code blocks in the notebook.
5. See error in screenshot

Expected behavior Expected the sparql query to interact with the Sagemaker endpoint and predict edges

Screenshots See attached

Desktop (please complete the following information):

• OS: Mac OS 11.6.4 (Big Sur)
• Browser Chrome
• Version 99.0.4844.74 (Official Build) (x86_64)

Additional context Note that the error messages involve the url in the PREFIX statements. Perhaps they have changed. I could not find any information in Neptune Docs specifying what they should be.
