Sticky notes doesn't support code blocks

[bastianfbr]

Bug Description

I was working on a great workflows with some comments and thought about giving some code notes with sticky notes in Markdown. I just added some code with the md syntax.

The thing is code should be formatted as a code block according to https://commonmark.org/help/ and https://markdown-it.github.io/ (the package that n8n use for sticky notes) but the preview is just made of many inline codes :

(Note that i just write some dumb code for example)

To Reproduce

1. Create a workflow
2. Add the sticky note :

   
   "meta": {
   "instanceId": "3bfec22f89ad299b5b96495128d71a8acbefb4ac174fd94ab6adbe4a78e34db3"
   },
   "nodes": [
   {
     "parameters": {
       "content": "## ERRORS\n\n```\nif (true === true) {\n   return false;\n}\n```",
       "height": 289,
       "width": 442,
       "color": 3
     },
     "id": "3ac5aa86-52a4-48f7-89bc-bcd72415b55b",
     "name": "Sticky Note2",
     "type": "n8n-nodes-base.stickyNote",
     "typeVersion": 1,
     "position": [
       620,
       520
     ]
   }
   ],
   "connections": {},
   "pinData": {}
   }```

Expected behavior

Preview should be a large code block like :

Operating System

Windows 11

n8n Version

1.57.0

Node.js Version

Database

SQLite (default)

Execution mode
