fix: Fixes regions having the wrong type (#1260)

## Possible Breaking Change
* Reverted regions.json back to RunUO until newer regions are implemented and proper expansion checks are added.

### Other Changes
- [X] Adds `Region.IsPartOf<T1, T2>()` to check for multiple types.
- [X] Fixes regions.json being wrong
- [X] Adds lots of missing regions. **They are not implemented properly yet**
- [X] Adds regions.xml -> regions.json (check ModernUO Discord)
- [X] Adds expansion specific regions.
