Introduction to TensorFlow Data Validation: accidentally clicked on tfdv_basic_spending_old.ipynb instead of tfdv_basic_spending.ipynb

Fat finger double clicked on the old file while trying to open the newer one in the jupyter notebook. I propose a cleanup.

(First numpy installations descends into a carnage:

Then later when I try to execute the second code bloc where the `tensorflow_data_validation` would be imported fails. Looking at the solution: doesn't have any package versions pinned, and more importantly the `tensorflow-data-validation` has a `--user` switch.)
