Some nested fields have been moved out of the Shop object and onto the QueryRoot in the Storefront API

As part of our efforts to improve the quality of the Storefront API, we've moved some nested fields out of the Shop object and onto the QueryRoot.

The following fields on the Shop object have been deprecated, and now return a deprecation warning:

• collectionByHandle
• collections
• productByHandle
• productTags
• productTypes
• products

These fields can now be queried directly on the QueryRoot.
