I think it would not hurt to give the $locale everytime to the callback method.

Example usage:

$notificationContent = $this->localeSwitcher->runWithLocale($contact->getLocale(), function(string $locale) use ($someEntity): string {
    $title = $someEntity->getTitle($locale);

    return $this->twig->render('template.html.twig', ['title' => $title]);
});

Alternative solution currently is:

$locale = $contact->getLocale();
$notificationContent = $this->localeSwitcher->runWithLocale($locale, function() use ($locale, $someEntity): string {
    $title = $someEntity->getTitle($locale);

    return $this->twig->render('template.html.twig', ['title' => $title]);
});

So this avoids creating a $locale variable which maybe only is necessary inside the callback method.
