feat: add optional fallback getter when parsing string with shortcodes

[ndelanou]

This makes it easier to parse user input that may contain non-existing shortcodes

[Nikoro]

There is already a method that covers this:

It's called getOneOrNull

So instead of changing thisgetOne method. You could use getOneOrNull directly then:

  String fromShortcodes({String Function(String unknownShortcode)? onUnknownShortcode}) {
    return _value.splitMapJoin(Regex.shortcode, onMatch: (m) {
      final match = m.group(0)!;
      return _emojis.getOneOrNull(match.removeColons())?.value ?? onUnknownShortcode?.call(match) ?? match;
    });
  }

I missed that 👍
