Implement TranslatableInterface for the ReadableEnumInterface

[laurentmuller]

Because the ReadableEnumInterface can be translated within the TranslatorInterface, it will be nice to implements also the TranslatableInterface to enums.

To translate readable enums is just matter to have a call as follow:

public function trans(TranslatorInterface $translator, string $locale = null): string
{
    return $translator->trans($this->getReadable(), [], $locale);
}

We then use in PHP:

NotifyType::EMAIL->trans($this->translator)

Or in Twig:

{{ supplier.notifyType|trans }}

We can maybe create a trait for that:

use Elao\Enum\ReadableEnumTrait;
use Symfony\Contracts\Translation\TranslatorInterface;

trait TranslatableEnumTrait {

    use ReadableEnumTrait;

    public function trans(TranslatorInterface $translator, string $locale = null): string
    {
        return $translator->trans($this->getReadable(), [], $locale);
    }
}

And in a enums:

use Elao\Enum\ReadableEnumInterface;
use Symfony\Contracts\Translation\TranslatableInterface;

enum NotifyType: int implements ReadableEnumInterface, TranslatableInterface
{
    use TranslatableEnumTrait ;

    #[EnumCase('notify.email')]
    case EMAIL = 0;
    #[EnumCase('notify.webhook')]
    case WEBHOOK = 1;
}
