Updates to the request

1. New Google Knowledge Graph Search API introduces two editions, Basic and Advanced. For more information, see Basic and Advanced editions.

https://kgsearch.googleapis.com/v1/entities

https://enterpriseknowledgegraph.googleapis.com/v1/projects/PROJECT_ID/locations/global/publicKnowledgeGraphEntities
