[Bug] NPC Roller does not respect Proficiency Without Level system setting

[dodgepong]

How to reproduce

1. Enable "Proficiency Without Level" variant rule in PF2e system
2. Open NPC Roller

Expected result

Roll modifiers would use values in line with the Proficiency Without Level rule variant (i.e. subtract the monster's level from the base modifiers)

Actual result

Modifiers maintain standard Proficiency With Level values

Additional details

Not sure if it's possible to hook into the PF2e variant rule setting or if it has to be enabled manually within PF2e Workbench's own settings, but this would help a lot with what is already a pain point when using this variant rule either way.

If there's another way to do this that I am missing, I'd be happy to be educated.
