* Update PyKatsina.yml file

* Added PyCon Arewa pycon-arewa.yml

PyCon Arewa is Northern Nigerian based annual Python Conference, it's a regional Python Conference dedicated to bringing together developers, students, educators, and professionals from the North to learn, share, and connect in the spirit of open-source and community growth.

* Added PyHausa

The Python Hausa Community is a pioneering initiative dedicated to promoting Python programming using the Hausa language — one of the most widely spoken languages in West Africa. It was founded to bridge the digital divide by making programming more accessible to native Hausa speakers, especially in underserved regions across Northern Nigeria and beyond.

This community is built on the belief that language should never be a barrier to learning technology. By localizing technical content into Hausa, the initiative empowers people to learn, build, and grow in tech without first mastering English through organizing events and conferences such as "PyCon Arewa" as international Python conference for Hausa-speaking individuals and translating Python Docs to Hausa language.
