Remove readiness probe from otel-agent sidecar

The readiness probe on the otel-agent container was causing operational issues:
- False alarms during slow cluster startup due to health check binding failures
- Inconsistent with other containers (git-sync, reconciler) which don't use readiness probes
- Redundant for a telemetry sidecar that doesn't provide direct user-facing services
