We have added the showExtensionErrorMessages property to the checkoutFlow method of the Browser SDK. This property lets you control whether to display a specific error message from the API extension instead of a generic fallback message. When you set address as true, extension-specific error messages for address validation are shown in the UI.

Additionally, we have updated the Browser SDK documentation to display types instead of placeholder values in the configuration properties table. This change provides developers with more accurate type information and a better overall experience.
