Most part of regions are wrong in Portuguese

The regions in Portuguese were not translated from English. We can see for example the structure of:

```
 "District of Columbia" should be "Distrito de Columbia"
"New York" should be "Nova Iorque"
"Hawaii" should be "Havaí"
"North Carolina" should be "Carolina do Norte"
```

Other countries also were wrong.
