install foris-controller-nextcloud-module with nextcloud

Up to the version 0.4.2, foris-controller-storage-module included both storage and nextcloud, but nextcloud was cut out into it's own module foris-controller-nextcloud-module.

AFAIK the foris-controller-nextcloud-module is not installed alongside nextcloud on TOS 5.2.0 when user selects NAS + Nextcloud package list.

Which means that there is no user friendly way to setup nextcloud, unless user somehow manage to install foris-controller-nextcloud-module package.
