Changes visible to users:

• Bug fix (prefix: fix - non-breaking change which fixes an issue)

Description

• call MarkdownRenderer.renderMarkdown(...); for list item description render

Motivation and Context

• Support showing tasks as indented #60

Reproduction:

1. Create a file called Test File with Nested List Items.md
2. Paste in this content

# Test File with Nested List Items

- [ ] #task *Do* they give **credit**?
    - I am **bold** text
    - I am *italic* text
    - I am a link to my own file [[Test File with Nested List Items]]

```tasks
path includes {{query.file.path}}
show tree
hide backlinks
```

3. View in Reading Mode or Live Preview

Result: The formatting characters in list items are displayed rather than being rendered:

Note: We should add a #tag sample too, to ensure that tags are rendered

I expect that if we changed the instanceof to something like closestParentTask.constructor.name === 'Task' we will remove the cyclic dependency problem (I think) we had when trying to move this code to ListItem.ts.
