fix: remove deprecation from agent passages endpoints (#9117)

* fix: remove deprecation from agent passages endpoints

The client.agent.passages endpoints (list, create, search, delete) were
incorrectly marked as deprecated. This would break significant amounts
of user code and negatively impact developer experience.

Fixes #9116
