[Fix] Fix tests for current helm chart otel configuration

[royischoss]

📝 Description

Fixed 13 failing tests in tests/helm-template-test.sh that were stale relative to recent OTel changes:

---

🛠️ Changes Made

• Collector test: updated expected upgradeStrategy from automatic to none (the new default in values.yaml).
• Instrumentation tests (Python + Java): added the missing --set opentelemetry.collector.enabled=true flag — the installer template needs the collector enabled to render.
• Jupyter test: flipped the assertion to confirm Jupyter does not get the mlrun.io/otel label, matching the intentional design (Jupyter is not auto-instrumented).
• Namespace-label test: removed the obsolete kubectl annotate assertion — instrumentation is now opt-in per pod, not namespace-wide.

Result: 67 passed, 0 failed (was 56/13). helm lint clean.
