The "Core concepts" section does not give descriptions to properties or types

Because suggest services are able to return descriptions for both properties and types (as well as items), this field should be mentioned in the Core concepts section:

• https://reconciliation-api.github.io/specs/latest/#types
• https://reconciliation-api.github.io/specs/latest/#properties
