Align Line to Support Bidirectional Text

[Bip901]

Current Behavior

Currently, lines are always aligned to the left. The file:

Test 123
فحص 123
בדיקה 123

Renders as:

Desired Behavior

Paragraphs/lines that begin with a "Strong" RTL character should be aligned to the right, like so:

This excludes "weak" leading characters, like - [ ]. For example, here, the first line should be aligned left-to-right, and the last 2 right-to-left:

- [ ] Test
- [ ] בדיקה
- [ ] فحص

Obsidian is another markdown editor that used to behave like FlutterMarkdownEditor, but ever since their 1.7.0 update - it works great with bidirectional text.

They use CodeMirror under the hood, maybe you can look at their BiDi (Bidirectional) implementation for inspiration?
