/**
* This workflow updates a cart's promotions, applying or removing promotion codes from the cart. It also computes the adjustments
* that need to be applied to the cart's line items and shipping methods based on the promotions applied. This workflow is used by
* [Add Promotions Store API Route](https://docs.medusajs.com/api/store#carts_postcartsidpromotions).
*
* You can use this workflow within your own customizations or custom workflows, allowing you to update a cart's promotions within your custom flows.
*
* @example
* const { result } = await updateCartPromotionsWorkflow(container)
* .run({
* input: {
* cart_id: "cart_123",
* promo_codes: ["10OFF"],
* // imported from @medusajs/framework/utils
* action: PromotionActions.ADD,
* }
* })
*
* @summary
*
* Update a cart's applied promotions to add, replace, or remove them.
*
* @property hooks.validate - This hook is executed before all operations. You can consume this hook to perform any custom validation. If validation fails, you can throw an error to stop the workflow execution.
