The reason just testing oldest and latest versions would not be sufficient with cudf.pandas is pandas-2.x especially has had multiple breaking changes across minor versions in-between too. That's why this testing.

The main thing is that we want to make sure that cudf.pandas will at least import normally for a wider range of packages. The way that cudf.pandas works, it is much easier to make a change that actually prevents import pandas as pd from working. We're OK if some particular bit of functionality only works with pandas 2.1.2 but not 2.0.1 because we can only realistically match exactly the behavior of one pandas version at a time due to all the edge cases in pandas behavior. We are not OK with a particular pandas version (supposedly within our supported range) being completely unusable.

One suggestion for improvement, otherwise seems fine.
