The documentation mention that the silent query parameter can be used when replacing a document with PUT /_api/document/{collection}/{key}.

https://www.arangodb.com/docs/stable/http/document-working-with-documents.html#replace-document

The PutDocumentAsync uses the class PutDocumentsQuery for passing query pameters, but this class does not contain a Silent property. I think we should create a PutDocumentQuery class specific to the PutDocumentAsync method.
