Add support for blockGap

With blockGap coming (for those themes who opt-in to it) to WP 5.9 later this month, it be excellent if GenerateBlocks containers could support it out of the box. Is there a chance this could be added? Please and many thanks!

I know even Automattic blocks like Layout Grid need to add support for it, but it would be awesome if we could have this in GenerateBlocks. :slight_smile:
