language() request needs to be 'GET' in APIS.py

[Isaha-Miller]

urllib is throwing a urllib.error.HTTPError: HTTP Error 405: METHOD NOT ALLOWED error because languages() is not specifying a GET request. The fix is to change line 82 req = request.Request(url, data=url_params.encode()) to an explicit GET.

def languages(self):
        """Retrieve list of supported languages.

        Returns: A list of available languages ex. [{"code":"en", "name":"English"}]
        """

        url = self.url + "languages"

        params = dict()

        if self.api_key is not None:
            params["api_key"] = self.api_key

        url_params = parse.urlencode(params)

        req = request.Request(url, data=url_params.encode(),method="GET")

        response = request.urlopen(req)

        response_str = response.read().decode()

        return json.loads(response_str)```
