[gnome-software/gnome-41: 1/2] snap: Use channel name in plugin cache key.

[Philip Withnall <pwithnall src gnome org>]

    snap: Use channel name in plugin cache key.
    
    The existing key didn't have the channel name, which stopped the alternates system from working.
    
    This was broken in d0747ba25e0381b4f0ceb0cd67e1bd4adb94f774
