/**
* This workflow creates, updates, or removes variants' prices. It's used by the {@link updateProductsWorkflow}
* when updating a variant's prices.
*
* You can use this workflow within your own customizations or custom workflows to manage the prices of a variant.
*
* @example
* const { result } = await upsertVariantPricesWorkflow(container)
* .run({
* input: {
* variantPrices: [
* {
* variant_id: "variant_123",
* product_id: "prod_123",
* prices: [
* {
* amount: 10,
* currency_code: "usd",
* },
* {
* id: "price_123",
* amount: 20,
* }
* ]
* }
* ],
* // these are variants to remove all their prices
* // typically used when a variant is deleted.
* previousVariantIds: ["variant_321"]
* }
* })
*
* @summary
*
* Create, update, or remove variants' prices.
