Enhanced createInventoryFeed mutation with new optional field type

We've added a new optional "type" field to the createInventoryFeed mutation, providing more control over data feeds:

• INCREMENTAL : Loads only new or modified data since the last execution, optimizing performance and reducing data transfer.
• FULL :                  Extracts the entire inventory dataset at each execution, ideal for inventory reconciliation and ensuring data consistency across platforms.
