Release 1.8.0 - New Payments Setups feature

[david-ruiz-cko]

This release introduces a new payments/setups package to support Payment Setup operations, including creating, updating, retrieving, and confirming payment setups. It also integrates the new Payment Setups client into both the ABC and NAS API entry points and adds comprehensive unit tests for the new functionality. Additionally, it improves type safety in the payments domain and updates CI workflows to use newer GitHub Actions versions.

Payment Setups feature:

Added a new payments/setups package with a Client that supports creating, updating, retrieving, and confirming payment setups via the API. This includes methods for each operation, with appropriate authorization handling and documentation.
Added a dedicated test suite in payments/setups/client_test.go to cover all Payment Setups client methods, including authorization failures and success cases.

SDK API integration:

Registered the new PaymentSetups client in both the abc/checkout_api.go and nas/checkout_api.go API entry points, making payment setup functionality available in both API variants.
