🥕[Bug]: JSON schema: Missing descriptions

[JerryNixon]

Several properties in the JSON schema are missing descriptions.

Recommendation

entities.<entity>.graphql.type.singular Add description: "Defines the singular GraphQL type name for the entity."

entities.<entity>.graphql.type.plural Add description: "Defines the plural GraphQL type name for the entity."

entities.<entity>.relationships.<relationship>.cardinality Add description: "Defines the cardinality of the relationship between entities."
