docs: Shows the man page packed inside the bubble tool
  
      this is mainly too overcome limitations on installing manual pages in a distribution agnostic and simple way
      and the way bubble has been developed, in virtual python environments,
      installing a man page into a system location makes no sense,
      the system manpage will not reflect the development version.
  
      and if your is system is really bare like : docker.io/python,
      you will not even have man installed
