    debugging: slides: remove incorrect unit of iostat
    
    The manpage states:
    
      Transfer rates are shown in 1K blocks by default, unless the environment
      variable POSIXLY_CORRECT is set, in which case 512-byte blocks are used.
    
    So it's not necessarily 512-blocks.
    
    Besides we get kB units in the example on the slide, as the default when
    running iostat on the labs image and on my Ubuntu 22.04.
    
    As the unit is very clear from the output, just don't mention any units.
