Add SellingPlanAllocation in Product

[abubakarflutter]

Hi, I want the Selling Plan Allocation in the Product example response is given below, you can view more details from the following link.

https://shopify.dev/docs/api/storefront/2024-01/objects/SellingPlanAllocation

1. As far i know, Selling Plan Allocation is the subscriptions on a certain product.
2. subscription will be set by enabling any subscription app from shopify store - here is the free Shopify Subscriptions
3. After enabling you have to add the subscriiption options for by selecting products and then those details will be fetched by this sellingPlanAllocation

here is the GraphQL query i used

      product(id: "$productId") {
        id
        title
        variants(first: 10) {
          edges {
            node {
              id
              quantityAvailable
              requiresShipping
              sellingPlanAllocations(first: 10) {
                edges {
                  node {
                    sellingPlan {
                      id
                      name
                      description
                      options {
                        name
                        value
                      }
                      priceAdjustments {
                        orderCount
                        adjustmentValue {
                          ... on SellingPlanPercentagePriceAdjustment {
                            adjustmentPercentage
                          }
                          ... on SellingPlanFixedAmountPriceAdjustment {
                            adjustmentAmount {
                              amount
                              currencyCode
                            }
                          }
                        }
                      }
                    }
                    priceAdjustments {
                      compareAtPrice {
                        amount
                        currencyCode
                      }
                      price {
                        amount
                        currencyCode
                      }
                      perDeliveryPrice {
                        amount
                        currencyCode
                      }
                    }
                  }
                }
              }
            }
          }
        }
      }
    }  ```

              "sellingPlanAllocations": {
                "edges": []
              }
            }
          },
          {

Hi @abubakarflutter

Thank you for opening the issue.

I have no plan to add the SellingPlanAllocation in the products yet. But I am always open for PR.
