Follow-up from #4637 (review)

There are several Jupyter notebooks in this repo which were generated with Python 3.9, which cugraph stopped supporting in the 24.10 release (#4637).

You can see them at https://github.com/search?q=repo%3Arapidsai%2Fcugraph+%223.9%22&type=code&p=2.

It may be useful to:

• test and regenerate them with the latest Python version RAPIDS supports (3.11 as of this writing, but 3.12 soon per Add support for Python 3.12 build-planning#40)
• update their copyright dates
• update any other details like:
  • range of supported CUDA versions
  • removing language about driver versions (update a few more Python references to Python 3.10 #4637 (comment))
