This changeset introduces the fhir-ig-us-core as a test dependency for
fhir-search. This was strictly out of convenience...the alternative
would be to create a new test-only PackagedRegistryResourceProvider that
provides multiple versions of the same search parameter(s).

otherwise we run into the following error during validation if us-core
is on the path:
```
SEVERE: validateResource(json/profiles/fhir-ig-us-core/Observation-some-day-smoker.json)
unexpected failure: Input resource failed validation:
generated-us-core-smokingstatus-5: Constraint violation:
effective.where(is(dateTime)).exists() (Observation)
```

I also added back in the fhir-examples.version variable because I think
our release automation still depends on this one (I had maybe
accidentally removed it while removing the other variables for
dependabot).
