No folding for objects with list value without identation

[amarao]

Description

Folding does not work with objects containing lists which are on the same indentation as parent element.

Steps to Reproduce

Example of yaml file:

---
example:
- one
- two

Place cursor on 'example' and press 'fold' (Ctrl-Shift-[)

Expected behavior: Folding of 'example' element

Actual behavior: nothing happens

Reproduces how often: 100%

Additional Information

If yaml file has additional indentation, folding works.

---
example:
 - one
 - two

The problem is that most of yaml-generating software (python-yaml, jackson yaml, etc) generate yaml with no additional indentation for lists by default (as in the bugreport example).

This would require a tree-sitter grammar for intelligent folding.
