fix: Use undefined for type attribute default

[mhemmings]

Changes Overview

#5344 introduced a type attribute for ordered lists. The default value is set to null which causes a change in the outputted document when using editor.getJSON(). If the user is using strict backend validation of the document, this will cause validation to fail.

Changing to undefined removes it from the JSON document, matching previous behaviour.

Pre v2.6.1

{
  "type": "orderedList",
  "attrs": {
    "start": 1,
  },
  "content": [],
}

Since v2.6.1

{
  "type": "orderedList",
  "attrs": {
    "start": 1,
    "type": null,
  },
  "content": [],
}
