Removed deprecated names of Product Variant Selection types

As announced before we have now removed the deprecated values from the type field of ProductVariantSelection. To assign Variants to Product Selections, use the IncludeOnly and IncludeAllExcept types instead.

Changes:

• [API] Removed inclusion and exclusion values from the type field of ProductVariantSelection.
• [GraphQL API] Removed the following types on the GraphQL schema: ProductVariantSelectionExclusion, ProductVariantSelectionInclusion.
