Added Notification to routeNotificationFor method

[SebastiaanKloos]

Added the Notification class to the routeNotificationFor method. I need to get the notification so I can return the webhook url based on the type of notification like so:

public function routeNotificationForWebhook($notification)
{
    if ($notification instanceof IssueStatusUpdatedNotification) {
        return $this->issue_custom_webhook;
    }

    return $this->custom_webhook;
}

It's the same as how it works with the Slack channel.

Thanks in advance for your time!

Will this PR be merged in the feature?
I need the possibility to set the url based on the notification and not on the notifiable.

+1 for this

[freekmurze]

Because...

• this change seems correct
• a lot of people seem to want it
• we need it as well for a project
• this project seems not actively maintained

... I've decided to step in merge this and tag a release that contains these changes.
