feat(oci): add ShareCoveX to the catalog and ask for the directories it shares

ShareCoveX is a file server with a web panel that publishes directories
over SMB, NFS or both. Its recipe declares that it shares directories, so
the installation asks for them one after another, in the default mode as
well: each is a container volume or a directory of the host, mounted under
/shares with the name given to it. Modify offers to add more.

The advanced installation also offers the privileged profile NFSv4 needs;
the default one never asks and stays unprivileged. A secret can declare a
minimum length, and the recipe opens the Files & Sharing category.
