Update banner

A map of localized destination URLs. The key is the language code (ISO 639 - set 1), e.g. "en", "de", "fr", etc. If you want to localize the URL for different regions of the same language, you can add the country code (ISO 3166-1 alpha-2), e.g. "en-US", "en-GB", etc.

A list of textual elements that should show on top of the banner, ordered vertically from top to bottom. The first element will be considered the "primary" and will appear more prominently.

A list of assets to be shown in the background (as the main banner image). Each asset is meant for a different screen size, determined by its breakpoint_width property. E.g. if you only want a single asset for this banner, you can set breakpoint_width to 0. E.g. if you want to show a different asset for mobile vs desktop, you can set breakpoint_width to 0 for the mobile asset and 1024 for the desktop asset.
