Outline: handle numbered lists

[andreoliwa]

Expected behaviour

Numbered lists are not supported by Logseq, but they should be handled anyway when converting flat Markdown to outline.

Current behaviour

Unknown; it has to be tested.

Steps to reproduce

1. Run poetry run lsd path/to/file.md with numbered lists.
2. Check what happens and adjust.

Possible Solution

Choose one of the possible ways to deal with numbered lists.

Convert numbered lists to...

• individual bullets (-) and remove the leading number (1., 2., etc.)
• individual bullets (-) and keep the leading number (1., 2., etc.)
• a single bullet (-) with a multi-line paragraph, keeping leading numbers and indenting the subsequent lines
