New v3 API endpoints for vendor bank account operations

When you create a vendor with vendor bank account information, BILL has restrictions for updating this bank account information. To stay consistent with this BILL policy, we have removed the ability to update vendor bank account information with the Update a vendor (PATCH /v3/vendors/{vendorId}) endpoint.

At the same time, we have introduced a set of endpoints for vendor bank account operations. You can now add and manage vendor bank account information with a dedicated set of endpoints.

NOTE

To update vendor bank account information, you must first delete the existing vendor bank account (with DELETE /v3/vendors/{vendorId}/bank-account), and then create a new vendor bank account (with POST /v3/vendors/{vendorId}/bank-account) with the updated information.
