[🐛 Bug]:extraVolumeMounts and extraVolumes cause template rendering failure in Helm chart under videomanager components

[ndambi2024]

What happened?

When using videoManager.extraVolumeMounts or videoManager.extraVolumes in the official Selenium Grid Helm chart, the Helm template fails with an error like:
json: cannot unmarshal object into Go struct field Container.spec.template.spec.containers.volumeMounts of type []v1.VolumeMount
This is caused by the template rendering the extraVolumeMounts and extraVolumes values incorrectly — treating them as objects rather than arrays.

Command used to start Selenium Grid with Docker (or Kubernetes)

Use this minimal values.yaml
videoManager:
  enabled: true
  extraVolumeMounts:
    - name: srv
      mountPath: /srv
  extraVolumes:
    - name: srv
      persistentVolumeClaim:
        claimName: my-pvc

Relevant log output

I believe the cause is found here: https://github.com/SeleniumHQ/docker-selenium/blob/selenium-grid-0.43.0/charts/selenium-grid/templates/video-manager/file-browser-deployment.yaml#L116

It seems to be injecting the entire yaml document instead of the extraVolumes fragment -- and same for extraVolumeMounts above that line.

Missing a with statement or something like that?
