Set resources to default in Paperless-NGX values.yaml

This commit modifies the `values.yaml` file for the Paperless-NGX Helm
chart by changing the configuration for resources under the controllers
section. The line for resource request/limits was previously commented
out, and this change officially sets the `resources` field to an empty
object (`{}`).

This update provides a clearer structure for users to configure resource
requests and limits for their container setup, allowing for easier
customization according to their deployment needs. No breaking changes
are introduced, but users should now be aware that they can specify
resource requirements directly in this section if desired.
