Pandas version checks

• I have checked that the issue still exists on the latest versions of the docs on main here

Location of the documentation

https://pandas.pydata.org/docs/user_guide/style.html

Documentation problem

The link to an online notebook-viewer, here –

and here –

– seems to be broken.

It points to the host nbviewer.ipython.org, which, though alive and responding to HTTP requests, keeps sending back 301 redirects which just point to itself, resulting in an endless loop.

Suggested fix for documentation

I assume the correct URL should point to https://nbviewer.org, which is up and working.

So the new URL would be https://nbviewer.org/github/pandas-dev/pandas/blob/main/doc/source/user_guide/style.ipynb.

This URL would be better than the existing documentation's because it works.
