Conflicting ELASTIC_PASSWORD among differently named secrets

[cawoodm]

Chart version: 7.17.3

Kubernetes version: 1.23

Kubernetes provider: K3S (on-prem)

Helm Version: 3

helm get release output:
nothing, not installed

Describe the bug:
Following the security example has resulted in an error when installing the chart:

W0105 13:23:15.573073 1310129 warnings.go:70] spec.template.spec.containers[0].env[18].name: duplicate name "ELASTIC_PASSWORD"

It seems the security Makefile creates a secret called elasticsearch-credentials which then conflicts with the chart's secret called elasticsearch-master-credentials.

The --dry-run generated YAML shows:

        env:
          - name: ELASTIC_PASSWORD
            valueFrom:
              secretKeyRef:
                name: elasticsearch-master-credentials
                key: password
          - name: ELASTIC_PASSWORD
            valueFrom:
              secretKeyRef:
                key: password
                name: elastic-credentials

The second entry with elastic-credentials comes from the security example and is in our values.yaml

Steps to reproduce:
See above.

Expected behavior:

Provide logs and/or server output (if relevant):

Be careful to obfuscate every secrets (credentials, token, public IP, ...) that could be visible in the output before copy-pasting
