Fix TelemetryOptionalImportError

✅ Solution

The "TelemetryOptionalImportError" usually arises when an optional dependency required by a specific feature (like an exporter or propagator) is missing. To fix this, identify the missing dependency from the error message and install it using pip; for example, `pip install grpcio` if the error mentions gRPC. Ensure your OpenTelemetry packages themselves are up-to-date too via `pip install --upgrade opentelemetry-sdk opentelemetry-exporter-otlp`.
