Numbered lists don't continue

[JenniBeadle]

Describe the bug
Numbered lists restart at 1 after subheading even when given a specific starting number after the heading.
Having just looked at the Notion markdown, I think it may be a Notion bug not a docu-notion bug.

Reproduction Steps
I have 25 chapters in my Paratext Manual. In the overview I break them up into sections but need the sequential numbering to continue so it shows correct chapter number.
Add a numbered list with headings.
Edit each list item after the heading with the number to continue.
Notion displays correctly.
But the resulting page restarts the numbering.

URL of a source Notion page that, when docu-notion accesses or converts it, shows the problem:
Notion: https://jennibeadle.notion.site/Overview-of-Training-Manual-3ce84f9ca3264aed8532489c0574f95c
Resulting page: https://sillsdev.github.io/paratext-manual/Overview/

Expected behavior
Numbering should continue (as per my other Docusaurus site.
https://manual.paratext.org/Training-Manual/Overview

Notion markdown
The notion markdown still has 1.

### Stage 1 Drafting

1. 2. **[OD** – Organising your desktop](https://sillsdev.github.io/paratext-manual/2.OD)
2. **[PP1** – Project plan and progress](https://sillsdev.github.io/paratext-manual/3.PP1)

I added the 2. to specify to continue from 2 but it still has the 1.
I corrected the markdown and pasted it again but it added the 1. again.

Additional context
I searched for possible solutions.

suggested putting a blank link before the element (in their case a code block) but had no effect.

Yeah, this was reported to Notion here, and I also tried with Notion's email support back in October, but didn't get anywhere.

I did have success indenting the text.

Not sure about indenting headings. But I guess I could turn the headings into text and bold them.

Doesn't work with non-indented bold text blocks. :(

Notion wrote back saying that they are not going to fix this in the API. So without that, we can't support this, sorry.

Anyone having this problem, please make yourself heard by writing to Notion. They rejected my request for a fix, but said that they might act on it if more people asked. So please ask! See: makenotion/notion-sdk-js#292
