Issue:
Bug: [FEATURE]: [Bambora] Use `connector_response_reference_id` as reference to merchant



### :memo: Feature Description

- Reference id are used to map transactions in the connector’s dashboard.
- Hyperswitch manages several reference ids, such as `payment_id`, `attempt_id`, and `connector_transaction_id` for a single transaction. 
- However, merchants may encounter uncertainty when determining which ID to utilize in the connector dashboard to identify the payment.

### :hammer: Possible Implementation

- When we receive a response from the connector for the payment, we deserialize it and populate the `response` field in RouterData. 
- For the `TransactionResponse` type, we must fill the `connector_response_reference_id` with a corresponding reference id for the merchant to identify the transaction. 
- One might need to have exposure to api docs of the connector for which it is being implemented to decide what to fill in connector_response_reference_id.
