provide country information based on the timezone

[adietish]

Telemetry is not allowed to reverse map the user IP address to the country that this IP sources from. We thus have to guess the country by the timezone that the user machine is set to.
The equivalent implementation for vscode is based on https://github.com/manuelmhtr/countries-and-timezones:
https://github.com/redhat-developer/vscode-redhat-telemetry/blob/main/src/utils/platform-node.ts#L15

export const COUNTRY = getCountry(TIMEZONE);
