Editing the Nextcloud config.php in CasaOS changes ownership from "www-data" to "root" [Bug]

[danieljonce]

Describe the bug
After a fresh install of Nextcloud in CasaOS running on Debian everything works as expected until a change is made to config.php using the text editor in CasaOS

To Reproduce

1. Install Nextcloud via CasaOS
2. Verify it's working correctly
3. Save a change to the /var/www/config/config.php file using the CasaOS text editor
4. Refresh Nextcloud, it will now throw an error "Cannot write into "config" directory!"

Expected behavior
I expect the previous file ownership "www-data www-data" to persist after a file change but it is changed to "root root"

The two ways I've found to work around the issue:

1. Use chown www-data:www-data var/www/html/config/config.php from the host OS console (not the Docker container) to change the ownership for config.php back to www-data www-data

OR

2. Set the flag 'config_is_read_only' => true, in the config.php, which works temporarily but during Nextcloud updates the config.php file needs to be writeable.
