chore(chart/supervisor): tpl-evaluate extraVolumes/extraVolumeMounts

Wraps the new extras with `tpl (toYaml .) $` so operators can embed
Go-template directives in their values (e.g. `{{ include
"trigger-v4.fullname" . }}` for ConfigMap/Secret names that vary by
release). Backwards-compatible — `tpl` over a value without `{{ }}`
is a no-op.
