Update documentation

On this page: https://processwire.com/modules/template-engine-twig/

• Current version is v3, not v2.

• This code is wrong:

wire()->addHookAfter('TemplateEngineTwig::initTwig', function (HookEvent $event) {
    /** @var \Twig_Environment $twig */
    $twig = $event->arguments('twig');
    $twig->addFunction(new \Twig_Function('processwire', function () {
        return 'ProcessWire rocks!';
    }));
});

This one is OK:

wire()->addHookAfter('TemplateEngineTwig::initTwig', function (HookEvent $event) {
    /** @var \Twig\Environment $twig */
    $twig = $event->arguments('twig');
    $twig->addFunction(new \Twig\TwigFunction('processwire', function () {
        return 'ProcessWire rocks!';
    }));
});

Oh, the module still displays an outdated version of the README of this repo (https://github.com/wanze/TemplateEngineTwig). It's correct there. Just can't login atm on ProcessWire, I thought that it should sync the readme automatically there?

I have no idea how it should work. :)
