Maybe can add another value to `folding_horiz_line` to make the horizontal line that shows up when code fold is collapsed/folded to be a bold/thicker line.

You are limited to what Scintilla allows, see [here](https://www.scintilla.org/ScintillaDoc.html#Folding). If its possible then "somebody" will need to make a PR to add the option.
