* Add ProductsControl component to search and select products
* Add “Hand-picked Products” block
* Update hand-picked & new product icons
* Prevent API request when no products are selected
* Remove rows setting
* Update shortcode/query helpers for the handpicked products
* Remove shortcode from post if no product IDs are passed
Rendering a shortcode with `ids=‘’` will show all products, as if the ids param wasn’t there. The expected outcome would be no products are shown, we we achieve by removing the shortcode.
* Remove unused rows attribute
* Update accessible spoken notice
* Add a variable to hold whether there are selected products
* Fix copy-paste comments
