Add effectiveDateTime to the example ADI documentation Observation

[smunini]

Summary

The US Core Observation ADI Documentation group has a SHALL patient + category + date search test. The example resource Observation/usqualitycore-us-core-observation-adi-documentation has no effective[x], so the test cannot find a date value and always skips against the kit's own example bundle:

Could not find values for all search params `patient`, `category`, `date`

It is the only skipped test when the us_quality_core_v100_ballot suite runs against a server loaded with client-example-resources/us_quality_core_bundle_patient.json.

Change

Add "effectiveDateTime": "2024-05-16T01:06:06Z" to that Observation. It is the same instant as the resource's issued, which is what the neighbouring usqualitycore-us-core-treatment-intervention-preference Observation does.

Observation.effective[x] is 0..1 and not must support in us-core-observation-adi-documentation 9.0.0, so the resource stays conformant and no must support expectations change.

Testing

Run in the Helios FHIR Server CI, which loads the example bundle and runs the us_quality_core_v100_ballot suite with patient_ids = usqualitycore-patient. Results to follow in a comment.

CI results

Run in the Helios FHIR Server CI: the server is loaded with client-example-resources/us_quality_core_bundle_patient.json, then the us_quality_core_v100_ballot suite runs with patient_ids = usqualitycore-patient (580 tests).

Test kit	Result	Run
v0.2.0 (41fc954)	578 pass / 1 skip / 1 fail, identical on 7 storage backends	35525950814
this branch (6e51b84)	579 pass / 0 skip / 1 fail	35536674380
this branch + #1 (4b8bc2b)	580 pass	35537188608, and 6 more backends in 35529459218

The one skip on v0.2.0 is us_core_observation_adi_documentation_patient_category_date_search_test. On this branch it runs and passes, including the comparator searches:

GET /Observation?category=observation-adi-documentation&date=2024-05-16T01:06:06Z&patient=usqualitycore-patient        -> 200
GET /Observation?category=observation-adi-documentation&date=gt2024-05-15T01:06:06+00:00&patient=usqualitycore-patient -> 200
GET /Observation?category=observation-adi-documentation&date=ge2024-05-15T01:06:06+00:00&patient=usqualitycore-patient -> 200
GET /Observation?category=observation-adi-documentation&date=lt2024-05-17T01:06:06+00:00&patient=usqualitycore-patient -> 200

No other test changed result. The remaining failure is the Simple Observation multiple-or search from issue 43, fixed in #1.
