Add missing Ethiopian states: Sidama (ET-SI) and Southwest Ethiopia Peoples (ET-SW)

[Copilot]

Summary

Fixes missing Ethiopian administrative divisions by adding two regional states that were absent from the database, bringing Ethiopia into full compliance with the ISO 3166-2:ET standard.

Issue

The database contained only 11 of the 13 Ethiopian administrative divisions specified in ISO 3166-2:ET. Two recently formed regional states were missing:

• Sidama (ET-SI)
• Southwest Ethiopia Peoples (ET-SW)

Both regions were formed by separating from the Southern Nations, Nationalities and Peoples Region (SNNPR) in 2020 and 2021 respectively.

Changes

1. Sidama Regional State (ET-SI)

• Type: Regional State
• Capital: Hawassa (ሀዋሳ)
• Coordinates: 6.5°N, 38.5°E
• Native Name: ሲዳማ
• WikiData ID: Q30107894
• Formation: 2020 (separated from SNNPR)
• Translations: 19 languages included

2. Southwest Ethiopia Peoples Regional State (ET-SW)

• Type: Regional State
• Capital: Bonga
• Coordinates: 7.3°N, 36.2°E
• Native Name: ደቡብ ምዕራብ የኢትዮጵያ ሕዝቦች
• WikiData ID: Q105085548
• Formation: 2021 (separated from SNNPR)

Future Work

After these states are imported to MySQL and assigned IDs, a follow-up PR should:

1. Reassign ~7 cities from SNNPR to Sidama region (including capital Hawassa)
2. Reassign ~5 cities from SNNPR to Southwest Ethiopia Peoples region (including capital Bonga)
3. Add additional cities for these regions as needed
