Drop n8n createDraftVersion, add body to update

Remove the createDraftVersion document operation from the n8n node and
instead expose the document body on the update operation. Updating the
body edits the current draft version, or creates one from the latest
published version when none exists, so a dedicated draft-creation
operation is redundant.

Also correct the content field help text across the document
operations: the API expects a ProseMirror document JSON string, not
markdown.
