Describe the bug
Having a line break between lists of checkboxes brakes MD parser

To Reproduce
Not sure what is the specific problem. But trying to parse this to blocks throws an error:

- [ ] asf

- [ ] asf

Uncaught (in promise) Error: blockContainer node does not contain a blockContent node in its children: blockContainer(blockGroup(blockContainer(checkListItem), blockContainer(paragraph(" asf"))))

Misc

• Browser: Google Chrome (I did it here: https://www.blocknotejs.org/docs/editor-api/converting-blocks)
• I'm a sponsor and would appreciate if you could look into this sooner than later 💖
