The 'ZERO' plural resolver for pt_BR is wrong

[emersonsiega]

Describe the bug
In Brazilian Portuguese, the zero is considered a plural.
Like: 0 apples, 0 transactions, and so on..

The Intl.plural is incorrectly resolving ZERO as ONE.

To Reproduce
Correct result for en_US:

import 'package:intl/intl.dart';

void main() {  
  final number = 0;
  final other = '0 apples';
  final one = '0 apple';
  
  final plural = Intl.plural(
      number,
      one: one,
      other: other,
    );
  
  print(plural); 
  //PRINTS: 0 apples
}

Incorrect result for pt_BR:

import 'package:intl/intl.dart';

void main() {
  Intl.defaultLocale = 'pt_BR';
  
  final number = 0;
  final other = '0 apples';
  final one = '0 apple';
  
  final plural = Intl.plural(
      number,
      one: one,
      other: other,
    );
  
  print(plural);  
  //PRINTS: 0 apple
}
