Documentation / Make file commands are out of date

[benfairclough]

The documentation vs the code is out of date, commandlets and been changed and are not representative to the documentation provided.

Examples : ~make in the directory errors out:: on list-supported-os:
list-supported-os
bash: line 1: LIST_VERSIONS_HELP_INFO: unbound variable
make[1]: *** [Makefile:37: list-supported-os] Error 1
make: *** [Makefile:188: help] Error 2

There is no defined commandlet for make run-artifacts-container although it does run

make list-versions does not work,

The described GIF in the documentation refers to folder structure which are not available hence is difficult to build images.

Please update accordingly.
