Produces invalid YAML

[Sebelino]

With let g:yaml_formatter_indent_collection=1, running :YAMLFormat on the following file:

repos:
- repo: https://github.com/pre-commit/pre-commit-hooks
  rev: v4.3.0
  hooks:
  - id: trailing-whitespace

produces:

repos:
  - repo: https://github.com/pre-commit/pre-commit-hooks
  rev: v4.3.0
  hooks:
    - id: trailing-whitespace

which cannot even be parsed. Expected:

repos:
  - repo: https://github.com/pre-commit/pre-commit-hooks
    rev: v4.3.0
    hooks:
      - id: trailing-whitespace
