Missing check boxes in task lists with indented text

## Environment

**App version:** GitJournal 1.74.3+2301
**Device information:**
- OS name and version: Android
- Manufacturer:
- Model:

## Description

**Expected behavior:**
Task lists with items separated by indented text should render with check boxes. For example,

```
- [x] item1
some text under item1
- [x] item2
```

should render with two check boxes.

**Current behavior:**
Task lists with items separated by indented text render as unordered lists with items separated by indented text. The check boxes are ignored. The example above renders the same as does

```
- item1
some text under item1
- item2
```
