/**
 * VirtualPages class.
 *
 * This class is responsible for generating virtual pages based on the configuration provided.
 * It extends the AbstractGenerator and implements the GeneratorInterface.
 * It collects pages from the configuration under the 'pages.virtual' key and creates Page objects
 * for each virtual page defined in the configuration.
 * Each page can have its own frontmatter, and the generator ensures that the pages are created
 * with the correct path and language settings.
 * If a page is marked as unpublished or does not have a path defined, it will be skipped.
 * If a page already exists with the same ID, it will also be skipped.
 * The generated pages are added to the collection of generated pages for further processing.
