Additional comments

Hello,

I would like to suggest a new rule called no-duplicate-definitions.

In Markdown, it’s possible to define the same definition identifier multiple times. However, this is usually a mistake, as it can lead to unintended or incorrect link, image references.

This rule is inspired by an existing one, remark-lint-no-duplicate-definitions.

If this suggestion is accepted, I’d be happy if you could assign it to me! I’ll make sure to complete it by May 14.
