bug: fix the indentation

[HarikrishnanBalagopal]

The yaml is not being rendered properly. The indentation is messed up.

This issue is present on multiple tutorial pages.

Example

Lines 129 to 158 in 106713d

	1. The `transformer.yaml` is the transformer configuration. We have [two changes](https://github.com/konveyor/move2kube/blob/main/assets/built-in/transformers/dockerfilegenerator/nodejs/transformer.yaml) here compared to the built-in transformer:
	- The name of our custom transformer is `Nodejs-CustomFiles` (see `name` field in the `metadata` section).
	- We are also specifying an `override` section which is asking Move2Kube to disable the transformer named `Nodejs-Dockerfile` if this transformer is present.
	```console
	$ cat customizations/custom-dockerfile-change-built-in-behavior/nodejs/transformer.yaml
	```
	```yaml
	apiVersion: move2kube.konveyor.io/v1alpha1
	kind: Transformer
	metadata:
	name: Nodejs-CustomFiles
	labels:
	move2kube.konveyor.io/task: containerization
	move2kube.konveyor.io/built-in: false
	spec:
	class: "NodejsDockerfileGenerator"
	directoryDetect:
	levels: -1
	consumes:
	Service:
	merge: false
	produces:
	Dockerfile:
	disabled: false
	DockerfileForService:
	disabled: false
	override:
	matchLabels:
	move2kube.konveyor.io/name: Nodejs-Dockerfile
