Support for auto-update with PDFs

[jhschwartz]

Is your feature request related to a problem? Please describe.
Zotero will not "keep updated" an export if the export is done with files. This results in the obsidian version of the reference library not having PDFs, which would be nice for easy in-obsidian reading.

Describe the solution you'd like
I'd like to be able to automatically sync my zotero library while also automatically being able to read PDFs of my references in obsidian. These PDFs would be linked to the obsidian notes created for each reference.

Describe alternatives you've considered
I've tried what's described briefly here but it doesn't make any sense (doesn't match available settings in zotero).
