Configure display setting of Dataframe in 2.0 tutorial

[JohnsonKuan]

Configure display setting of Dataframe in 2.0 tutorial to address issues with background color of header in dark mode for docs.

Background color of rows will be addressed in another PR after 2.0 tagging.

Won't this be visible in the docs build and in the colab notebook?

[jwmueller]

At least need to replace metadata above with:

"metadata": {
    "nbsphinx": "hidden"
   },

That will at least hide in the docs website.

[JohnsonKuan]

Yes I believe so, the code will be visible. I'm not sure how to hide it though.

[jwmueller]

Actually if you want to add this stuff to this notebook it should go into the cell that is already hidden (the one starting with # Package installation.).

I'd add it before/after:

%config InlineBackend.print_figure_kwargs={"facecolor": "w"}

We should not have many hidden cells in one notebook, it makes the colab / local versions look too different from the docs website one.

[JohnsonKuan]

Sounds good, agree. I moved it to the cell that is already hidden.

LGTM. Double check jonas's comment. After merge, double check it worked (takes a few minutes to load) and double check these settings and weird code blocks are not visible to user.
