// The store card shows the registry fields added after 3.7.0 -- the commit
// that introduced the listed version and a warning when the plugin needs a
// newer core -- and still renders a card from an older registry that has
// neither. isStorePluginInstalled also answers to an entry's `aliases`.
//
// Rendered with the shipped functions (extracted from plugins_manager.js).
