Version 1.6.6: Versionsanzeige im Info-Dialog bei PyInstaller-Bundle gefixt

Im PyInstaller-Bundle fehlten .dist-info-Metadaten, wodurch importlib.metadata
keine Paketversionen liefern konnte. Lösung: DocuMentor.spec erzeugt beim Build
einen Versions-Snapshot (versions.json) der ins Bundle eingebettet wird.
license_parser.py liest diesen Snapshot im Bundle-Modus statt importlib.metadata.
