Clean install failing as NC tries to write config itself.

Describe your Issue

Fresh install, nothing in PV helm chart creates config and submounts all kinds of files there.
Then When openeing URL in Browser it just says

"It looks like you are trying to reinstall your Nextcloud. However the file CAN_INSTALL is missing from your config directory. Please create the file CAN_INSTALL in your config folder to continue."

Logs and Errors

No errors in logs

Describe your Environment

• Kubernetes distribution: k3s 1.33

• Helm Version 3.19.1

• Helm Chart Version: 9.0.3

• values.yaml:

# pv and ingress stuff, shouldnt affect anything, otherwise just
image:
  imagePullPolicy: Always

internalDatabase:
  enabled: true

nextcloud:
  password: xxxxxx

  host: "nextcloud.xxxx"
  mail:
    smtp:
      host: "xxxx"
  configs:
    trusted_proxies.config.php: |-
      <?php
      $CONFIG = array (
        'trusted_proxies' => array('192.168.0.0/248', '10.0.0.0/8'),
      );
        

Reproduce a clean install using the supplied values.yaml and inspect the Helm chart's PV and config-related templates. Confirm which mounted files are created and how Nextcloud writes its config; done when a fresh deployment reaches the browser without reporting that CAN_INSTALL is missing.
