Missing GraphQL Product fields

[themreza]

The latest version of the storefront integration throws the following GraphQL error when searching for a product:

 WARN   [GraphQL error]: Message: Cannot query field 'imageFilename' on type 'Product'., Location: line: 32 | column: 7).join(' '), Path: null                                                                                22:24:31
 WARN   [GraphQL error]: Message: Cannot query field 'jsonLd' on type 'Product'., Location: line: 35 | column: 7).join(' '), Path: null                                                                                       22:24:31
 WARN  [Network error]: ServerError: Response not successful: Received status code 400                     

The error suggests that fields imageFilename and jsonLd are missing on the Product type.

Adding the fields in https://github.com/odoogap/vuestorefront/blob/14.0/graphql_vuestorefront/schemas/objects.py#L267 fixes the issue:

json_ld = graphene.String()
image_filename = graphene.String()

I'm not sure about the actual usage of these fields, and it's still throwing the following warnings due to the fields not being defined:

 WARN   [GraphQL error]: Message: 'product.template' object has no attribute 'image_filename', Location: line: 32 | column: 7).join(' '), Path: products,products,11,imageFilename                                            22:31:18
 WARN   [GraphQL error]: Message: 'product.template' object has no attribute 'json_ld', Location: line: 35 | column: 7).join(' '), Path: products,products,0,jsonLd       

The demo website does have the correct fields:

The code seems to be on the 15.0 branch, but not on 14.0: https://github.com/odoogap/vuestorefront/blob/15.0/graphql_vuestorefront/schemas/objects.py#L305

The same file has multiple differences between 14.0 and 15.0. Please double check the codebase. https://www.diffchecker.com/ByCexBxC
