Update PyRIT to v0.9.x

[marcorosa]

PyRIT has been updated and part of its functionalities that we were using have been moved/deprecated.

In particular:

• ScoringRedTeamingOrchestrator class: pyrit/orchestrator/scoring_red_teaming_orchestrator.py
• SupportTextClassification class: pyrit/score/support_text_classification.py

We need to replace them in order to update pyrit to more recent versions (v0.3+, currently we are at 0.5.2).

Updates need to be ported into this file
