Update recent group changes for Govern and Analytics

What does this MR do and why?

• The new Govern stage resulted in the deprecation of one group (Container Security) and the addition of a new group (Security Policies).
• Analytics introduced a new group: Product Analytics.

This MR updates the TW rake task so the CODEOWNERS file is updated correctly when this task is run.

Assignments have been made according to: https://about.gitlab.com/handbook/product/ux/technical-writing/#designated-technical-writers
