[bitnami/mongodb] Empty-Dir volume is missing in the default arbiter node configuration

[SeWieland]

Name and Version

bitnami/mongodb 14.12.0

What architecture are you using?

amd64

What steps will reproduce the bug?

Deploy the chart with default values and replicaset architecture with arbiter node.

In version 14.12.0, the arbiter node declares mounts of the "empty-dir" volume.
However, the empty-dir volume only gets created conditionally using:

{{- if or .Values.arbiter.configuration .Values.arbiter.existingConfigmap .Values.arbiter.extraVolumes .Values.tls.enabled }}

Are you using any custom parameters or values?

No response

What is the expected behavior?

The empty-dir volume should be created unconditionally

What do you see instead?

The arbiter pod cannot be created:

create Pod mongodb-arbiter-0 in StatefulSet mongodb-arbiter failed error: Pod "mongodb-arbiter-0" is invalid: [spec.containers[1].volumeMounts[0].name: Not found: "empty-dir", spec.containers[1].volumeMounts[1].name: Not found: "empty-dir", spec.containers[1].volumeMounts[2].name: Not found: "empty-dir", spec.containers[1].volumeMounts[3].name: Not found: "empty-dir"]

As a workaround I simply added

arbiter:
  # Workaround for https://github.com/bitnami/charts/issues/23905
  extraVolumes:
  - name: dummy-dir
    emptyDir: {}

To my values yaml until this issue gets resolved
