Feature: Ability to customize Markdown nested list spacing

Nested lists in markdown can work with two or four base units of spaces

For flexibility reasons, Lexical should allow consuming and emitting markdown, with a configurable amount of whitespace.

It looks like this is a "known issue" as the source code indicates this should be configurable

I've ended up "patching" lexical in the short term, but would love for this to be built in!
