fix: only show unlisted project chip when it's the main project

[SylvainChevalier]

Closes #4687

Summary

Hides unlisted project chips in the question page sidebar when the unlisted project is a secondary project. Unlisted projects are still shown when they are the question's main (default) project.

Implementation

Added a filter in sidebar_question_projects.tsx that drops any project with visibility === ProjectVisibility.Unlisted unless its id matches default_project.id.
