Bug #19258: URI::Generic#host returns empty string instead of nil

On Ruby 3.1, URI::Generic#host would return nil for unix:/// URLs, but on Ruby 3.2 it now returns an empty string:

uri = URI.parse("unix:///var/run/docker.sock")
uri.host #=> 
# Ruby 3.1: nil
# Ruby 3.2: ""

This introduced a regression in the Excon gem, which currently doesn't handle these URLs on Ruby 3.2, because it aborts for UNIX URLs when :host is not nil.

This is an intentional change. See https://hackerone.com/reports/156615

Thanks or the update, makes sense, I will try to get Excon updated then.

Thanks for trying Ruby 3.2 quickly.
