How do I instrument CircleCI with OpenTelemetry?

    # Install OpenTelemetry dependencies
    composer require open-telemetry/opentelemetry

    # Initialize OpenTelemetry in CircleCI configuration
    $tracer = OpenTelemetry\Trace\TracerFactory::getTracer('example-service');
    $span = $tracer->startSpan('build');

    try {
        // Your CircleCI build tasks go here
        
    } finally {
        $span->end(); // End span at the end of the build
    }
