Example basic-delivery incorrect guidance on inspecting App resource

Bug description:

Two issues:

1. The README for the basic-delivery example says to run:

kubectl get app gitops -o yaml | yq -r .status.inspect.stdout

yq -r is not valid syntax (probably left over from a modified jq command?). Instead, this should be:

kubectl get app gitops -o yaml | yq .status.inspect.stdout

2. The README says the output from this command should show a handful of Knative resources. See here.

This output is actually only accessible through kapp inspect -a gitops-ctrl, but the App resource status only shows 2 resources and it is not entirely clear what they are. Here is the output of both the kbectl/yq command and the kapp command:

$ kubectl get app gitops -o yaml | yq .status.inspect.stdout
Target cluster 'https://10.96.0.1:443'
Resources in app 'gitops-ctrl'
Namespace  Name  Kind     Owner    Conds.  Rs  Ri                Age

Succeeded

Steps to reproduce:

For issue 1: Follow the instructions for basic-delivery example or use another resource at your disposal to validate that yq does not have a -r flag.

For issue 2: Follow the instructions for basic-delivery example and notice the discrepancy between the guidance in the README and the results of the command.

Expected behavior:

Commands returns proper status information for App resource

Actual behavior:

Issue 1: Command with -r flag returns error and usage instructions:

$ k get app gitops -o yaml | yq -r .status.inspect.stdout
Error: unknown shorthand flag: 'r' in -r
Usage:
  yq [flags]
  yq [command]

...

Issue 2: The output of the command does not match the sample output in the README.
