Module 2 - inconsistent terminology: TTP vs Scenario

[bluesentinelsec]

Some module 2 content does not consistently use the term "TTP Outline", instead it uses "Scenario Outline."
TTP Outline is the preferred term, as it is less ambiguous than Scenario, and also aligned with ATT&CK vernacular.

Module 2 slides 38 and 39 need to be changed, and correpsonding videos need to be edited.
