DOC: getting_started tutorials broken nbviewer link

[egeozguroglu]

Pandas version checks

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

Documentation problem

This tutorial link (currently on the documentation) - to a Jupyter Notebook - is broken, given the change in nbviewer link structure from nbviewer.ipython.org to nbviewer.org.

Suggested fix for documentation

Line 116 of doc/source/getting_started/tutorials.rst needs to be changed into * Financial analysis in Python, by Thomas Wiecki <https://nbviewer.org/github/twiecki/financial-analysis-python-tutorial/blob/master/1.%20Pandas%20Basics.ipynb>_
