Can not mount Volume to sidecar only

[hket-tommyluk]

Name and Version

bitnami/nginx 18.3.1

What architecture are you using?

None

What steps will reproduce the bug?

1. Use the nginx helm chart.
2. In values.yaml, apply the custom parameters in the next part.
3. Render the helm chart

Are you using any custom parameters or values?

values.yaml:

sidecars: |-
  - volumeMounts:
      - name: vol
        mountPath: /vol
    //...

extraVolumes: |-
  - name: vol
    configMap:
      name: cm

What is the expected behavior?

Successfully render templates

What do you see instead?

This should be a valid usage but the validation in NOTES.txt is blocking me from doing this.

Error: execution error at (nginx/templates/NOTES.txt:71:4): 
VALUES VALIDATION:
nginx: missing-extra-volume-mounts
    You specified extra volumes but not mount points for them. Please set
    the extraVolumeMounts value
