Describe task does not work for inline task spec

[piyush-garg]

Expected Behavior

tkn taskrun describe taskrun_name

This should show the description of taskrun

Actual Behavior

tkn taskrun describe task-59p7t          
Failed to execute templateError: template: Describe taskrun:3:21: executing "Describe taskrun" at <.TaskRun.Spec.TaskRef.Name>: nil pointer evaluating *v1alpha1.TaskRef.Name

Steps to Reproduce the Problem

1. Create a taskrun with inline spec like

apiVersion: tekton.dev/v1alpha1
kind: TaskRun
metadata:
  generateName: task-
spec:
  taskSpec:
    steps:
      - name: test
        image: ubuntu
        command: ["/bin/bash"]
        args:
          - -c
          - |
            set -e
            set -x
            echo hello world

2. Get the taskrun name

tkn taskrun list           
NAME         STARTED         DURATION     STATUS      
task-59p7t   2 minutes ago   13 seconds   Succeeded

3. Hit describe command

tkn taskrun describe task-59p7t          
Failed to execute templateError: template: Describe taskrun:3:21: executing "Describe taskrun" at <.TaskRun.Spec.TaskRef.Name>: nil pointer evaluating *v1alpha1.TaskRef.Name

We need to make sure this is also the case for PipelineRun too (with ResourceSpec too).
See:

• Adding support to enable pipelineSpec pipeline#1333
• Adding support to enable resourceSpec pipeline#1324

Is there a way to check if a field exists within the template? This is due to .TaskRun.Spec.TaskRef.Name not being present.

This would also be nice to figure out for use cases like displaying the status of a step as part of tkn taskrun describe.

We could also potentially look at adding a method to formatted to check if a field is present on the TaskRun spec.
