Reason:
Run error.

Suggestion:

1. Update BasicTracer to BasicTracerProvider
2. Remove const { setTracer } = require ("@azure/core-tracing")
3. Update setTracer(tracer) to opentelemetry.trace.setGlobalTracerProvider(tracer)
4. Update tracer.startSpan to tracer.getTracer().startSpan
5. Update opentelemetry.setSpan to opentelemetry.trace.setSpan.
