v3.5.33

This release adds a built-in tutorials browser inside BlocksJr, available from the Book section, so users can access BlocksJr activities and tutorials without relying on the host app.

Added a new Tutorials tab under Book in BlocksJr home.
Added an in-app tutorials page that lists all built-in BlocksJr tutorials.
Fixed tutorial launch flow for standalone and host-entry usage.
Changed tutorial close behavior so it always returns to the BlocksJr tutorials page.
Fixed tutorial title localization issues that were showing String missing.
Added numbering to Marty and Cog tutorial titles.
Adjusted the Book footer UI to support the extra Tutorials tab cleanly.
Added test coverage for tutorial fetching and tutorial open/close navigation flows.
