[Intl] format to feminine ordinal numbers

[JorickPepin]

As mentioned in this issue, the addition of the Intl extension should have enabled the display of feminine ordinal numbers through the format_ordinal_number filter (e.g. 1re instead of 1er in French), but is this really the case? If so, how could this be achieved? Thanks in advance.

In the current implementation, i think you'd code it quicker by yourself in a dedicated extension... than with the IntlExtension.

As you can see in the createNumberFormatter() method, the only way to set textAttributes would be to inject a $prototype ... but even then, you'd only can set "feminine" or "masculine" once.

Or you can try to find another way to add this behaviour line 511 (if the $textAttrs in not usable as right now)

        foreach ($textAttrs as $name => $value) {
            $this->numberFormatters[$hash]->setTextAttribute(self::NUMBER_TEXT_ATTRIBUTES[$name], $value);
        }

        foreach ($symbols as $name => $value) {
            $this->numberFormatters[$hash]->setSymbol(self::NUMBER_SYMBOLS[$name], $value);
        }

+        $this->numberFormatters[$hash]->setTextAttribute(self::NUMBER_TEXT_ATTRIBUTES['default_ruleset'], '%digits-ordinal-feminine');

        return $this->numberFormatters[$hash];
    }
}
