Opensearch extraOutputs values for the aws-for-fluent-bit chart are never retrieved

[jphilaire]

Describe the bug
We tried to configure opensearch extraOutputs for the aws-for-fluent-bit chart but the specified values are never retrieved.

It seems that there is a typo in the configmap.yaml file (stable/aws-for-fluent-bit/templates/configmap.yaml) at line 451.

The line is:

{{ .Values.opensearch.extraOutputsIndent_8 }}

it should be:

{{ .Values.opensearch.extraOutputs | Indent 8 }}

Steps to reproduce
In the helm values file for the opensearch output of the aws-for-fluent-bit chart, we have the following configuration:

opensearch:
  enabled: true
  match:   "*"
  host:    <HOSTNAME>
  port:    "443"
  tls:     "on"
  ...
  extraOutputs: |
    tls.verify off
    tls.debug  4

Expected outcome
In the generated fluent-bit.yaml configuration file, we should see something like this:

[OUTPUT]
    Name        opensearch
    Match       *
    Host        <HOSTNAME>
    Port        443
    tls         on
    ...
    tls.verify  off
    tls.debug   4

Environment

• Chart name: aws-for-fluent-bit
• Chart version: 2.28.4
• Kubernetes version: 1.24
• Using EKS (yes/no), if so version? eks.6
