Error parsing if link containing parentheses

[le.chang]

Summary

It is an old bug since gitbook, but still reproduce now. It is a parsing error of markdown file, caused by dependency library markdown-it (if i not mistake). It is fixed in latest markdown-it, maybe we need upgrade its version?

• HonKit version: 4.0.4

Step to reproduce

1. A book page as markdown format
2. create a link text whose url contains parentheses

• Link to code example:

[Pola](https://en.wikipedia.org/wiki/Pola_(Italian_province))

Expected results

<p><a href="https://en.wikipedia.org/wiki/Pola_(Italian_province)">Pola</a></p>

Actual results

<p><a href="https://en.wikipedia.org/wiki/Pola_(Italian_province" target="_blank">Pola</a>)</p>
