Write a new notebook demonstrating Weighted Jaccard

[acostadon]

Jaccard now supports weighted edges. Need a notebook to replace or add to existing notebook to demonstrate it. Possible using the dining tables dataset.

notebooks/algorithms/link_prediction/Jaccard-Similarity.ipynb

python/cugraph/cugraph/datasets/metadata/dining_prefs.yaml

Might need to add directionality to this dataset.
