Vscode-yaml: Add Config for Array Indentation Spacing

[codytwinton]

I'm working with Jekyll for GitHub Pages, which uses the Ruby gem for parsing YAML. This gem prefers this spacing in Arrays:

---
simple_val: Testing 1
object_val:
  sub_object_val: Testing 2
array_val:
- Testing 3
- Testing 4

However, when auto-formatter is on, this gets converted to:

---
simple_val: Testing 1
object_val:
  sub_object_val: Testing 2
array_val:
  - Testing 3
  - Testing 4

Regardless of preference, it would be great to have an option to disable adding space indention for arrays.

This all depends on prettier adding this configuration or seeing if they have some api that allows to change array configuration.

And per https://github.com/prettier/prettier/issues/4723, Prettier is decided to stay at do indent in mapping.
