Which resulted in a summary item in the sidenav

Just wondering if this is intentionally not there anymore, or maybe its missing.

[pettinarip]

Good observation. The thing is that this is not something I have added support for, because now every heading will appear in the sidebar. So I made that heading bold to avoid having it in the sidebar.

Then, in the case of the Summary section, this is a special case that I also didn't add support for. It is special because it has a hidden heading in the content. With this implementation we would have to add a heading like ### Summary to appear in the sidebar.

Let me see if we can do something about that.

This bold section at the top looks different between prod and this PR

[pettinarip]

Correct. I've answered this also in the prev comment but in short, now every heading in the md file will appear in the sidebar, so we will need to tweak it a bit to avoid that.

I've added a Summary component + a hasSummary frontmatter prop to display the summary link in the sidenav 4fa8069

@corwintines I've fixed the mentioned issue with the Summary link and also the issue detected in #341 (comment)
