Support PDF Export Via Pandoc

[jag3773]

Is your feature request related to a problem? Please describe.
Using Pandoc to export my markdown files gives me messed up checkboxes and does not make use of the beautiful checkbox styling from the theme. I use a script to convert several markdown notes to PDFs on a regular basis, the pandoc command in these scripts is:

pandoc --quiet --pdf-engine pagedjs-cli --css ~/.obsidian/themes/Minimal/theme.css "$x" -o "${x}.pdf"

Generally this works well but it generates ugly checkboxes:

Describe the solution you'd like
I would like to see a css file that works with pandoc's pagedjs-cli PDF engine to implement the custom checkbox styles in the minimal theme. This would yield output similar to Obsidian's native PDF output:

(Note that the exclamation mark checkbox item is actually styled by the List Callouts plugin which I'm migrating away from...)
