Write a notebook with a tutorial for Abul-Naga & Yalcin index implementation based on the tutorial here: https://github.com/hs3city/ordinal-scale-stats-py/blob/main/dev-notebooks/allison-foster-index.ipynb

Abul-Naga & Yalcin index takes two parameters alpha and beta (read docstring here: https://github.com/hs3city/ordinal-scale-stats-py/blob/3dccb46d0ae156d55f04d0d4f6026759e62b9b25/src/abul_naga_yalcin_index.py#L60 ).

The tutorial should show three different scenarios:

1. Alpha = 1, Beta = 1
2. Alpha = 1, Beta = 4
3. Alpha = 4, Beta = 1

It is a boilerplate. Thus, no additional description in the markdown is needed.
