Code Review

This pull request updates the transfers service by renaming the CapitalApi class and its corresponding accessor to CapitalDeprecatedApi, and introducing a new CashOutApi service with an initiate_cashout endpoint. Feedback on these changes highlights that renaming the public capital_api method is a breaking change for SDK consumers. It is recommended to retain capital_api as a deprecated alias that delegates to capital_deprecated_api and issues a deprecation warning to preserve backward compatibility.

[gemini-code-assist]

Renaming the public method capital_api to capital_deprecated_api is a breaking change for users of this SDK who are currently calling client.transfers.capital_api.

To maintain backward compatibility and prevent breaking existing integrations, please retain the capital_api method as a deprecated alias that delegates to capital_deprecated_api and outputs a deprecation warning.

    def capital_deprecated_api
      @capital_deprecated_api ||= Adyen::CapitalDeprecatedApi.new(@client, @version)
    end

    def capital_api
      warn "[DEPRECATION] `capital_api` is deprecated. Use `capital_deprecated_api` instead."
      capital_deprecated_api
    end
