/**
 * Nested subcategory renderer for the Doc Category Archive List widget's
 * Layout 2 and Layout 3.
 *
 * Mirrors the Layout 1 call in template-parts/category-list.php, but buffers
 * the output so the load-bearing `betterdocs-articles-list` wrapper — the
 * stylesheet hides the collapsed arrow via
 * `.betterdocs-articles-list .betterdocs-nested-category-title svg.arrow-down`
 * — is emitted only when there is something to render. template-parts/
 * nested-categories returns early for a term with no renderable children,
 * which would otherwise leave a stray empty <ul> carrying list spacing on
 * every childless category.
 *
 * @var bool          $nested_subcategory
 * @var \WP_Term|null  $current_category
