Enforce `-` for lists

• [x] check if markdownlint allow this (answer: yes)
• [x] check if automatic fix is available (answer: not yet)

Markdownlint allows this check, it is sufficient to add this to .markdownlint.yaml:

MD004:
  style: dash

The bad news is that it is not automatically fixed with markdownlint -f '**/*.md'. @simonsan do we still want to enforce this?

[simonsan]

If it's not automatically fixable probably not 🤔

[marcoieni]

I think we can consider this issue blocked by this, right?

[simonsan]

Yep!
