// We needed to change the size of the icon without affecting already existing blocks.
// This is why we are registering a new variation with a different icon class instead of changing directly the icon
// size in the css. By giving it the same name and making it default we are making sure that new blocks will use the
// new icon size and existing blocks will keep using the old one after updating the plugin.
// For more context, see https://github.com/woocommerce/woocommerce-blocks/pull/8594
