Add triggered badge to pipeline views

What does this MR do and why?

Add triggered badge to pipeline views.

It can be very useful to see on a pipeline level if it was triggered with a trigger token.
This information is already presented on the job tables, but not on the pipeline tables.

That information is now also visible on the pipeline level.
