change separate collections to one "resources" collection

## Use Case

we don't always know which resources someone wants to add 

## Acceptance Criteria

one resource collection: 
has Type: "software tool", "dataset" etc 
 
can add as many as you want 

## Details

can the flow be: pick a type, ie "Software" and get specific fields for that?
ie software we'd want to have a README/Quickstart link
