Description

The error message was previously in the format

{
    "error": {
        "type": "invalid_request",
        "message": "This refund is not possible through Hyperswitch. Please raise the refund through {connector} dashboard",
        "code": "HE_03"
    }
}

Here the connector should have been replaced by the actual connector name. This has been fixed in this PR.

Motivation and Context

Display the actual connector name.

How did you test it?

• Create a payment by klarna connector.
• Create a refund
