Issue:
[FEATURE]: [Bambora] Use `connector_request_reference_id` as reference to the connector

### :memo: Feature Description 

- We transmit our reference id from Hyperswitch to the connector, enabling merchants to subsequently locate the payment within the connector dashboard.
- Presently, there is a lack of uniformity in this process, as some implementations employ `payment_id` while others utilize `attempt_id`.
- This inconsistency arises from the fact that `payment_id` and `attempt_id` correspond to two distinct entities within our system.

### :hammer: Possible Implementation 

- To mitigate this confusion, we've introduced a new field called `connector_request_reference_id` in our RouterData. 
- This id should replace them as a reference id to the connector for payment request. 
- One might need to have exposure to api docs of the connector for which it is being implemented.
