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/getting_started/comparison/index.html

Documentation problem

I teach pandas, and have a number of students that come in with experience in SPSS. We have comparison guides with a number of other related tools, but none that speaks to SPSS.

Suggested fix for documentation

Add a "Comparison to SPSS" page
