Permit to add additional volumes for sidecar containers in statefulset.yaml

[fgionghi]

I'm using vaultwarden-backup as a sidecar container, but it also needs to mount a second volume for its configuration. At the moment I can't do it with your chart.

I achived that with the little modification I'm proposing
Then, in my values.yaml I'm using it as I would do in a normal statefulset:

additionalVolumes:
  volumes:
    - configMap:
        name: vaultwarden-backup-rclone-config
      name: vaultwarden-backup-rclone-config

Is there anything still left to be done before this feature can be added?

LGTM - if you're adding a feature, could you bump the minor version of Chart.yaml please?

Perhaps some documentation should also be added as this changes the available values?

It's possible the contributor might no longer be active. Someone can submit the PR, otherwise, I can also add the changes myself.
