MDbook Includes trigger alot of false positives

**What got flagged?**
```md
{{#include ../../partials/stages.md:pre}}
```

**Why is this incorrect?**
Mdbook allows including files and partials.

This allows not repeating some information in docs, and increases maintainability.
those includes shouldn't be flagged at all, or there should be a flag to ignore anything inside `{{ }}`

Reproduce the false positive with the shown mdBook include snippet, then read the linked mdBook inclusion documentation and trace how Markdown template syntax is analyzed. Done means the include is no longer incorrectly flagged, or an explicitly supported way to ignore content inside `{{ }}` is documented and tested.
