ci: call OpenTelemetry orchestrator workflow

[zhongkechen]

Summary

• call the reusable OpenTelemetry orchestrator workflow directly
• configure the orchestrator with the Python SDK settings previously supplied by the language wrapper
• add a workflow contract test and run it in the GitHub script test job

Testing

• pytest .github/scripts/tests/test_build_lambda_layer.py .github/scripts/tests/test_opentelemetry_conformance_workflow.py .github/scripts/tests/test_parse_sdk_branch.py -q
• Ruff check and format validation for the new test
• YAML parsing and git diff --check

No actionable findings. Residual risk is limited to runtime behavior of the pinned external reusable workflow, which is outside this diff.

This is a well-scoped CI-only change. The workflow now calls the generic opentelemetry-orchestrator.yml (same pinned SHA 397d523d…) with the Python settings passed explicitly, and the python_sdk_ref → sdk_ref rename preserves the identical ${{ github.event.pull_request.head.sha || github.sha }} resolution for pull_request/push/workflow_dispatch. The updated contract test in .github/scripts/tests/test_opentelemetry_conformance_workflow.py is internally consistent with the proposed workflow: every asserted string is present, and the relaxation from "otlp_endpoint:" to "\n otlp_endpoint:" is required (the new collector_otlp_endpoint: input contains the old substring) while still guarding the deprecated bare input without false-positiving on collector_otlp_endpoint:. The test is wired into test-parser.yml, satisfying the repo's test requirement for a CI-config change.

Residual test risk: The contract test is purely a text-substring check — it does not validate that the external opentelemetry-orchestrator.yml at the pinned SHA actually declares the inputs now being passed (language, resource_prefix, sdk_repository, checkout_sdk, contract_test_command, adot_release_repository, collector_compatible_runtime, collector_otlp_endpoint, suite_timeout_minutes, and the retained phase/delay_seconds/aws_region). If the orchestrator's input contract differs, the caller would fail at dispatch time, and this in-repo test would not catch it. This is unverifiable from within this repository; confirming it requires checking the orchestrator definition in aws/aws-durable-execution-conformance-tests at that revision.
