chore: Helm: Add sidecarVolumeMounts and extraVolumeMounts volumes to all sidecars

[oleksiytsyban]

Description
It is possible to add more than one sidecar container to Values.controller.sidecarContainer section, but volumes from sidecarVolumeMounts and sidecarVolumeMounts are added only to the last sidecar container. This change is to ensure that each sidecar container receives the appropriate volume mounts.
