tests: Add Integration with starter-projects Endpoint and Vector Store Test (#3599)

* ✨ (App.tsx): Add useGetStarterProjectsQuery hook to fetch starter projects data
📝 (constants.ts): Add STARTER_PROJECTS constant to define the endpoint for starter projects API
📝 (use-get-starter-projects.ts): Create useGetStarterProjectsQuery hook to fetch starter projects data
📝 (index.tsx): Add AppWrapperPage test for drag and drop functionality with starter projects data
📝 (starter-projects.spec.ts): Add end-to-end test for drag and drop functionality with starter projects data

* ✨ (starter-projects.spec.ts): update test description to be more descriptive and specific about the test scenario

* ♻️ (App.tsx): remove unused useGetStarterProjectsQuery hook to clean up code and improve readability

* 🔧 (App.tsx): remove unused import useGetStarterProjectsQuery to clean up code and improve readability
