Make the title "Highlight" an optional feature.

[Morganwan90]

Hello, after reading many reviews, I finally decided to use Omnivore and Logseq to manage my article highlights.

I've noticed that in the recent updates, every article now includes a third-level title "Highlight". I completely understand that some people need this feature, but could it be made optional, just like "## Article"?
