TZNames.GetAbbreviationsForTimeZone() for 'nb-NO' throws System.Exception: Could not find a language with code nb-NO

Happens for versions 5.0.0 and 5.0.1

Works fine for version 4.2.0

Hmmm.. I'll have to investigate further. Thanks.

Indeed, this is still happening on 6.0.0.

var results = TimeZoneNames.TZNames.GetNamesForTimeZone("America/Los_Angeles", "nb-NO");
Console.WriteLine(results.Generic);
