command(s?) in documentation don't work.

[mikedlr]

In the main documentation there is a command

$ kubectl label node kind-control-plane node.kubernetes.io/exclude-from-external-load-balancers-
node/kind-control-plane unlabeled

This command does not work. I believe that it should be something like

kubectl label node --overwrite kind-2-control-plane node.kubernetes.io/exclude-from-external-load-balancers=true

instead - probably better if the prompt isn't included in the copied text. It might be good if the documents were automatically tested e.g. with https://github.com/JNRowe/shell-doctest

that might get a bit expensive since you'd need the requisites setup.

they're also probably not changing often.

I agree that we should have copyable commands.

I think that the answer to this bug is that the wrong highlighting code is in use in the documentation

```sh
prompt$ some command
some result
````

prompt$ some command
some result

should be

```console
prompt$ some command
some result
````

propmt$ some command
some result
