ModuleNotFoundError: No module named 'opentelemetry.exporter' even though the package opentelemetry-sdk has been installed

What happened?

Describe the bug
I followed the Tracing and Observability tutorial in the documentation exactly but encountered the following issue:

Traceback (most recent call last):
  File "C:\Users\GV631HJ\OneDrive - EY\Desktop\KNF\main.py", line 9, in <module>
    from opentelemetry.exporter.otlp.proto.grpc.trace_exporter import OTLPSpanExporter
ModuleNotFoundError: No module named 'opentelemetry.exporter'

I have already installed opentelemetry-sdk package in my Python environment using pip install <package_name> command, and verified its installation with pip show <package_name>, confirming its presence:

(venv) PS C:\Users\GV631HJ\OneDrive - EY\Desktop\KNF> pip show opentelemetry-sdk
