AttributeError: module 'openai' has no attribute 'OpenAI'

Start with bertopic/backend/_openai.py and the import path shown in the traceback, then reproduce the failure with the reported pip install and import commands. Done means importing BERTopic no longer raises the reported AttributeError with the supported OpenAI dependency setup.
