Idea of new rule: use slash instead of backslash for image path

Correct:

![foo](images/foo.jpg)

Not recommended:

![foo](images\foo.jpg)

What's the state of this rule? It seems that markdown document written in typora use backslash for image path, it make the image broken in gitlab.

It sounds like a fairly straightforward rule to implement if anybody wants to do so for npm or as a custom rule in their repository. I have not added it to the core library so far.
