Fix protocols faq

[ranand]

Proposed changes

• We shipped Duplicate Tracking Plans and Libraries in Q3 (Public Beta) and moving to GA in Q4.
• PRD: https://docs.google.com/document/d/1b6jr7CsBk_YNJAvcATNOVi8bgCQi6P0ZtlVWkL5GxAk/edit#heading=h.vv9txf1zeg8
• In this PR, I propose that we fix the FAQ for Protocols to ensure we call out the ability to copy/duplicate tracking plans.

Merge timing

• Merge on 10/24/2022.
