markdown: nested lists should require 2 space, not 4
Created by: Necroskillz
Gitlab markdown behaves inconsistently for nested lists. for the 2nd level, it's renders correctly with 2 spaces, but then for deeper levels it requires 4 spaces. This breaks lists generated by https://github.com/jsdoc2md/jsdoc-to-markdown a bit.
Example: source:
* level 1
* level 2
* level 3
* level 4
with 4 spaces for level 3 & 4: source
* level 1
* level 2
* level 3
* level 4
github renders it correctly with 2 spaces:
- level 1
- level 2
- level 3
- level 4
- level 3
- level 2
