fix(pdf-burner): Korrektur des Versatzes von Siegelbildern für Tintenunterschriften

- Hinzufügen des Parameters „yOffset“ zu „AddImageAnnotation“, um die Position der Siegel anzupassen.
- Aktualisierung von „AddInstantJSONAnnotationToPDF“, um den Versatz für das erste Unterschriftssiegel anzuwenden.
- Stellt sicher, dass Tintenunterschriftssiegel in PDF-Dateien korrekt dargestellt werden, ohne andere Anmerkungen zu beeinträchtigen.
