Update Jupyter notebook

[icaoberg]

The Jupyter Notebook linked in this page.

Need to update the links

search_instance = hubmap_sdk.SearchSdk(service_url='https://search.api.hubmapconsortium.org/')
entity_instance = hubmap_sdk.EntitySdk(service_url='https://entity.api.hubmapconsortium.org/')

I would do it myself but I don't know where this notebook lives.
