Remove InventoryBin Delete/Upsert Mutations and Related Types

The unstable Shopify GraphQL API has dropped the InventoryBinDelete and InventoryBinUpsert mutations. All payload, error, and input types associated with those mutations – InventoryBinDeletePayload, InventoryBinDeleteUserError, InventoryBinDeleteUserErrorCode, InventoryBinUpsertPayload, InventoryBinUpsertUserError, InventoryBinUpsertUserErrorCode, and InventoryBinInput – have been removed from the schema. These mutations were only available in the unstable version and for development stores with the Physical inventory feature preview, so they never existed in the stable API. If your application relied on deleting or upserting inventory bins through GraphQL, those calls will now return a validation error or be unavailable. No direct replacement is provided in this schema, meaning you must remove or replace that functionality with an alternate approach. Developers should update their schemas and clients to reflect the absence of these fields and stop referencing them in queries and mutations. All other queries, mutations, directives, and types remain unchanged, so functionality outside of inventory blanks management is unaffected.
