JQ merge WooCommerce REST API responce

Question

Im trying to parse data from woocommerce from linux console. Need to take only shipping info and item names with quantity.

im making curl request to wp-json/wc/v2/orders/ORDER_ID
then jq '{order_id:.id,ship_info:.shipping,items: (.line_items[] | {name , quantity} ) }'
If order contains two items, jq will return two objects
example:

{
  "order_id": 1234,
  "ship_info": {
    "first_name": "Sam",
    "last_name": "Fisher",
    "company": "",
    "address_1": "24 Mega Drive",
    "address_2": "",
    "city": "Eglinton",
    "state": "WA",
    "postcode": "6032",
    "country": "AU",
    "phone": ""
  },
  "items": {
    "name": "Black T-shirt",
    "quantity": 1
  }
}
{
  "order_id": 1234,
  "ship_info": {
    "first_name": "Sam",
    "last_name": "Fisher",
    "company": "",
    "address_1": "24 Mega Drive",
    "address_2": "",
    "city": "Eglinton",
    "state": "WA",
    "postcode": "6032",
    "country": "AU",
    "phone": ""
  },
  "items": {
    "name": "White T-shirt",
    "quantity": 1
  }
}
                                                                                       
                                                                            

I want merge items and use item's name as a key and item's qty as a value. Please advice how to get output like this

{
  "order_id": 1234,
  "ship_info": {
    "first_name": "Sam",
    "last_name": "Fisher",
    "company": "",
    "address_1": "24 Mega Drive",
    "address_2": "",
    "city": "Eglinton",
    "state": "WA",
    "postcode": "6032",
    "country": "AU",
    "phone": ""
  },
  "items": {
    "White T-shirt": "1",
    "Black T-shirt": "1"
  }
}
