Add a Back Button to Question Page for Better Navigation

### Problem Statement:

Currently, when questions are displayed on the `Question.jsx` component, there is no way to navigate back to the previous page. To return, users must close and reopen the extension, which is inconvenient and disrupts the user experience.

### Steps to Reproduce:

1. Open the EduAid Chrome extension.
2. Navigate to the "Your Previous Work!" section.
3. Select any item to view the questions displayed in `Question.jsx`.
4. Notice that there is no option to navigate back.

### Proposed Solution:
Add a back button to the `Question.jsx` component. Clicking this button should take the user back to the main page or section.

### Benefits:

- Improves user experience by providing seamless navigation.
- Avoids the need to close and reopen the extension.
