Fix: quote nextcloud.objectStore.s3.legacyAuth value when rendering as env var

[jessebot]

Description of the change

This quotes the nextcloud.objectStore.s3.legacyAuth value when rendering it as an env var in _helpers.tpl. I think that's why it wasn't working before.

Benefits

Without this fix, setting the value to true doesn't work.

Possible drawbacks

We could also just have it be this to be more explicit, since the with will ignore a value of false anyway:

{{- with .Values.nextcloud.objectStore.s3.legacyAuth }}
- name: OBJECTSTORE_S3_LEGACYAUTH
  value: "true"
{{- end }}

Either should solve the issue 🤷
