DOC: Spelling should "focusing" rather than "focussing" in README.rst of documentation #7847
Description
Issue with current documentation:
From here: https://www.pymc.io/about/ecosystem.html
CausalPy: A package focussing on causal inference in quasi-experimental settings.
Idea or request for content:
Just correct the spelling. Maybe I should do it just to familiarize myself with PyMC's contribution process?
