Description

Currently, when a pipeline fails, the Finally task is executed. I can trigger a failed or succesfull Finally with (as an example):

      when:
        - input: $(tasks.status)
          operator: in
          values: ["Failed"]

However, $(tasks.status) does not provide information about which task failed. I would like to see a parameter that is passed to the Finally task, indicating which task failed This information could be used in a script to post to GIT (comit/PR) for example, indicating which task failed and why and maybe provide some context.

I've tried tasks[*] for example. But that doesnt work (see https://tekton.dev/docs/pipelines/variables/)
