[Product] Update the Composition resource downloads to trigger `$` operations

[dubdabasoduba]

Describe the feature request.

• The SDC allows the usage of ValueSets and CodeSystems for options on questionnaire items. It however needs the ValueSets to be expanded
• The ValueSet expansion is handled by HAPI via the $expand operation. e.g {{base_url}}/ValueSet/IMMZ.C.DE5/$expand
• We would like to be able to trigger this expansion via Compostion resources i.e if the reference on the Composition resource reference e.g

{
  "title": "IMMZ.C.DE5",
  "focus": {
    "reference": "ValueSet/IMMZ.C.DE5/$expand",
    "identifier": {
      "value": "IMMZ.C.DE5"
    }
  },
  "mode": "working"
}

Acceptance criteria

• [ ] Add the ability to trigger the ValueSet expansion via the references on the Composition resources
