Fix French cities native property mistranslations

The native property of 2,478 French cities was filled with what appears to be automatic mistranslations, resulting in nonsensical values.

{
  "id": 39305,
  "name": "Albi",
  "state_id": 4799,
  "state_code": "OCC",
  "country_id": 75,
  "country_code": "FR",
  "latitude": "43.92980000",
  "longitude": "2.14800000",
  "native": "eau de Javel", // literally means "bleach"
  // ...
}

The only change in this PR is setting the native property to match the name property for all French cities.
