Country content: Fix plugin... again

* Replace all references to freegeoip.app (which stopped working in late April) with country.is and api.country.is
* Rename country_code JSON key to country
* Overview of country.is:
  * Has existed since 2014-2015
  * Site claims not to collect request logs
  * Doesn't have any usage limits according to lineofflight/country#17
  * Discovered it in public-apis/public-apis#geocoding
* Successor to wet-boew#8928
