":include" in double quotes doesn't recognized

[zdm]

Bug Report

Steps to reproduce

Try to embed external file using for example this link:

[readme](https://raw.githubusercontent.com/softvisio/core/main/README.md ":include")

What is current behaviour

Currently file will not be embedded, because :include tag is placed in double quotes.
This is the problem, because prettier markdown processor replaces single quotes with double and double quotes are legal for the link title.

What is the expected behaviour

I am expecting, that file will be embedded ti the parent document.
