Updated Bank code mapping in Collect webhook

Previously bank codes were mapped as follows -

"bank_codes": [
        {
          "key": "swift_code",
          "value": "swufbkr"
        }
      ],

To bring parity among all Tazapay objects , now bank codes in collect webhook (In both destination_details and payer_bank_details) will be mapped as following -

"bank_codes":
        {
          "swift_code": "swufbkr"
        }  

Here is an example webhook response
