Azure.Monitor.OpenTelemetry.Exporter 1.8.3

Azure.Monitor.OpenTelemetry.Exporter version 1.8.3 includes a security fix that hardens ingestion and Live Metrics redirect handling to prevent forwarding telemetry to untrusted destinations. This update ensures redirect targets use HTTPS and match approved Azure Monitor trust boundaries, protecting against credential and telemetry exposure to attacker-controlled endpoints.
