Allow autoPublish for user types

[FlorianBoe]

👋 Hi Maurice, thanks for this great plugin!
The new version has also turned out very well.

I have a use case that cannot be implemented with the plugin at the moment, but I think it could be quite helpful to others as well.

I have a comment area where comments should be published automatically depending on the user type (blueprint). For example, all admins or editors. However, this list is dynamic and cannot be mapped using a static array of e-mail addresses in the config.

I think the function could be solved by moderation.autoPublish not only accepting an array, but also a closure that returns the permitted e-mail addresses. Like…

'autoPublish' => function () {
	$allowedEmails = [];
	$users = kirby()->users()->filter(function($user) {
		return $user->blueprint()->name() === 'users/admin' || $user->blueprint()->name() === 'users/editor';
	});

	foreach($users as $user) {
		$allowedEmails[] = $user->email();
	}

	return $allowedEmails;
}

What do you think?
