Currently, the Pipeline tutorial uses git and image PipelineResources for Task inputs/outputs see here. As there are beta-supported alternatives for both PipelineResources ([for git](https://github.com/tektoncd/pipeline/blob/master/docs/migrating-v1alpha1-to-v1beta1.md#replacing-a-git-resou

We're missing error handling for cancelling a run 🙈

Expected Behavior

We use a helper function to generate rawExtension objects needed in tests

Actual Behavior

Currently manually setting an []byte with inline json string in quite a few tests which makes the tests brittle.

Versions and Operating System

• Kubernetes version:

  Output of kubectl version:

  Client Version: version.Info{Major:"1", Minor:"10+", GitVersion:"v1.10.0+b3b92b2", GitCommit:"b3b92b2", GitTreeState:"clean", BuildDate:"2020-07-15T09:27:21Z", GoVersion:"go1.14.3", Compiler:"gc", Platform:"linux/amd64"}
  Server Version: version.Info{Major:"1", Minor:"19", GitVersion:"v1.19
  

This should:

1. Delete all knative resources (in all namespaces)
2. Delete the files used in mink install with --ignore-not-found.

Expected Behavior

Text says:

Any of the above options will fetch the image using the ImagePullSecrets attached to the ServiceAccount specified in the PipelineRun. See the Service Account section for details on how to configure a ServiceAccount on a PipelineRun. The PipelineRun will then run that Task without registering it in the cluster allowing multiple versions of the same named Task t
