[gparted] Add "Available online only" to the Supported Actions legend (#774818)

[Curtis Gedak <gedakc src gnome org>]

commit 5cd1f718a139d10037f0bf85a8baff34e8a7b691

    Add "Available online only" to the Supported Actions legend (#774818)
    
    Shrinking LUKS encryption is only possible while the mapping is open and
    active.  Therefore the File System Support dialog shows Cross + Tick for
    this operation.  Add this new combination to the legend.
    
    Bug 774818 - Implement LUKS read-write actions NOT requiring a
                 passphrase
