Deprecated Python SDK is used in the code

[Sygyzmundovych]

I see that best-practices/generative-ai/access-to-generative-ai-models/python/requirements.txt includes generative-ai-hub-sdk in the list.

But that package https://pypi.org/project/generative-ai-hub-sdk/ has been deprecated and should be replaced with the https://pypi.org/project/sap-ai-sdk-gen/

Regards.
