Skip bind mounts

[GPla]

The script changes the permissions for the named volumes like projects, logs etc.
It fails for user-added bind mounts ,e.g,

volumes:
  - ./some_folder:/opt/plcnext/some_folder

This change skips volumes without a name (other types of mounts).

Alternatively, one could check the type of mount and apply ACLs to the bind mount if so desired:

volumes=$(podman inspect $container_id --format '{{ range .Mounts }}{{.Type}}:{{ .Name }}:{{ .Source }}:{{ .Destination }} {{ end }}')

IFS=':' read -r volume_type volume_name volume_source container_path <<< "$volume"

if [ "$type" = "volume" ]; then
    volume_mnt=$(podman volume mount $volume_name)
elif [ "$type" = "bind" ]; then
    continue # or volume_mnt="$volume_source"
else
    continue
fi
