support mermaid syntax : mermaid-cli

It's a pain when a markdown file contain an invalid mermaid syntax

I'm unsure there is a formatter, but at least syntax could be used to generate image and so lint them

BTW, I found nothing about mermaid in mdsf but this

mdsf/mdsf/src/generated.rs

Line 566 in b02f5d1

"mermaid" => Some(".mmd"),

I'm unsure where this mermaid line comes from

Wouldn't image generation require the user to input some kind of filename?

The lines in that file is generated from this file https://github.com/github-linguist/linguist/blob/main/lib/linguist/languages.yml.

You are creating temporary local file for the source, then you delete it?

It differs from classic workflow indeed, but I think you can try to your filename suffixed with .png, and delete it too once generated.
