As a user I want to see which journey failed in the slack notifcation. Currenlty I see only which plan failed.
I also want to configure how I want to show the notifcation (eg show it with a screenshot or without)
You can now see in Slack the exact journeys that failed for a given plan run. For example, the attached image shows the 3 journeys that failed for a plan that run 6 journeys in total.
