[BUG] regression_blog_notebook.ipynb results do not match blog results

[miguelusque]

Describe the bug
Hi,

I am reading the following blog, and when I try to reproduce the example notebooks, the results do not match.

https://medium.com/rapids-ai/essential-machine-learning-with-linear-models-in-rapids-part-1-of-a-series-992fab0240da

In my testing, the best result is always MSE_OLS_THEORY, and not MSE_RIDGE, as stated in the blog.

Any ideas why is this happening? Could the code be updated to make reproducible results similar to the blog?

Steps/Code to reproduce bug
I am usign todays rapids nightly build from Dockerhub.

I have git cloned the notebooks-contrib repo (master, v0.11) and run the cells.

Expected behavior
Same results as in the blog.

Environment details (please complete the following information):
DGX-1
