The term 'segments' in the AEP documentation requires to be replaced with 'audiences'

Issue in ./help/tutorial-data-architect-and-engineer/build-segments.md

The 'segments' section in the documentation is visible as 'audiences' in the tool right now. And the term 'audiences' is used everywhere in the tool where 'segments' are used in the documentation screenshots and videos.
