Deprecating the Ability to Set Available Quantities on Already Active States on the InventoryActivate GraphQL Mutation

As of Admin GraphQL API version 2024-10, we're deprecating the ability to set the available quantity on the InventoryActivate GraphQL mutation for already active states. Moving forward, use the InventorySetQuantities GraphQL mutation instead. This change will take into full effect starting on the 2024-10 version of the Admin GraphQL API.
