[claudiubee]

Describe the bug
transactionAffiliation / affiliation should be set per item.
Current event payload for purchase (with Send Google Analytics 4 Events active):

dataLayer.push({
  event: "purchase",
  ecommerce: {
    transaction_id: "1333180500286",
    value: 5085.66,
    tax: 0,
    shipping: 5,
    coupon: null,
    items: [
      {
        item_id: "55",
        item_name: "G-Series G55-1850 Supercore Standard Rotation 85MM Comp Ind",
        item_brand: "Demo",
        item_variant: "76",
        price: 5080.66,
        quantity: 1,
        item_category: "Supercores",
        dimension1: "",
        dimension2: "880547-5001S",
        dimension3: "G-Series G55-1850 Supercore Standard Rotation 85MM Comp Ind",
        dimension4: "available"
      }
    ],
    currency: "USD"
  },
  gtm.uniqueEventId: 309
})

Expected payload:

dataLayer.push({
  event: "purchase",
  ecommerce: {
    ...
    items: [
      {
            affiliation: "Seller Demo",
      }
    ],
    currency: "USD"
  },
  gtm.uniqueEventId: 309
})
