Use k8sattributes processor's native support for service attributes

[ChrsMark]

The k8sattributes processor now supports natively Service attributes' handling based on Semantic Conventions' guidance: https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/v0.127.0/processor/k8sattributesprocessor/README.md#configuring-recommended-resource-attributes

We should consider using this natively instead of manually extracting from labels i.e. at

opentelemetry-helm-charts/charts/opentelemetry-kube-stack/templates/_config.tpl

Lines 134 to 144 in c166294

	- tag_name: service.name
	key: app.kubernetes.io/name
	from: pod
	- tag_name: service.name
	key: k8s-app
	from: pod
	- tag_name: k8s.app.instance
	key: app.kubernetes.io/instance
	from: pod
	- tag_name: service.version
	key: app.kubernetes.io/version
