Argo Empty Fields Facet: reduce to only 2 possible values

[ndushay]

Argo's Empty Fields facet is currently populated thus in production:

The goal for this ticket is to change the argo configuration so it only shows 2 values:

• No MODS typeOfResource
• No SW Resource Type

I believe that should be done here: https://github.com/sul-dlss/argo/blob/72ee31b069007813b57ed42971a7349595188de9/app/controllers/catalog_controller.rb#L156-L177
