Issue reported by: Applause - Internal Team
Slack conversation:

Action Performed:

1. Go to staging.new.expensify.com
2. Go to any chat
3. Type >>>>> in the composer

Expected Result:

The composer displays | >>> (Android and iOS app behavior)

1. Limit max depth of the quote inside ExpensiMark
2. change implementation of blockquotes in chat to show multi-level quotes
3. Enable inside react-native-live-markdown library support for multilevel quotes on all platforms - here won't be any limit, as parser should handle it.

Discussion for expected result https://expensify.slack.com/archives/C01GTK53T8Q/p1707904106957409

Actual Result:

The composer shows | > | > | instead of | >>>>>

@thienlnam @tomekzaw I think we jumped the gun here as we don't support multi-level blockquote yet. I think we need to implement these in ExpensiMark.

Offending PR found. This is the one related to markdown preview.
