fix: add fragments to headings

[vladh]

🔗 Linked issue

This fix was trivial so I decided to just create a PR.

🧭 Context

On the blog, headings do not have fragments, so cannot be linked to:

<h2>The need for npmx</h2>

📚 Description

I used markdown-it-anchor to automatically add fragments to headings:

<h2 id="the-need-for-npmx" tabindex="-1">The need for npmx</h2>
