Add wget to test_notebook dependencies (#3918)

Running certain notebooks requires downloading datasets via https://github.com/rapidsai/cugraph/blob/branch-23.10/notebooks/cugraph_benchmarks/dataPrep.sh which uses `wget`, so this PR ensures the `test_notebooks` environment created in `rapidsai/docker` will have `wget` installed.
