Invalid example on Kubernetes Prometheus and OpenMetrics metrics collection page

Kubernetes Prometheus and OpenMetrics metrics collection

Issue Description

The Advanced configuration example incorrectly uses a map for additionalConfigs when that field only supports the string type as defined here. Also see the example here.

Current doc:

apiVersion: datadoghq.com/v2alpha1
kind: DatadogAgent
metadata:
  name: datadog
spec:
  global:
    credentials:
      apiKey: <DATADOG_API_KEY>

  features:
    prometheusScrape:
      enabled: true
      enableServiceEndpoints: true
      additionalConfigs:
        - autodiscovery:
            kubernetes_container_names:
              - my-app
            kubernetes_annotations:
              include:
                app: my-app
          configurations:
            - timeout: 5
              send_distribution_buckets: true

Should be updated to:

apiVersion: datadoghq.com/v2alpha1
kind: DatadogAgent
metadata:
  name: datadog
spec:
  global:
    credentials:
      apiKey: <DATADOG_API_KEY>

  features:
    prometheusScrape:
      enabled: true
      enableServiceEndpoints: true
      additionalConfigs: |-
        - autodiscovery:
            kubernetes_container_names:
              - my-app
            kubernetes_annotations:
              include:
                app: my-app
          configurations:
            - timeout: 5
              send_distribution_buckets: true
