feat: Added Interview settings page functionality

Context

This pull request addresses issue #13 - the Interview Settings Functionality. Users can now set their preferred interview settings before beginning their interview practices.

Closes #13

What Changed?

• Added options for settings so that the user can freely change the Number of Questions, Question Type, Reading Time, Answer Time, and Answer Type.

  How To Review

• Test by clicking the arrow buttons in the settings page, see if the settings are being changed as desired.

  Testing

• I've tested all settings and edge cases, so that the 'time' settings does not go below 0 (no negative values)

  Risks

  NA

Thank you for adding the Interview settings page functionality -Nice start! The feature is working so looks good to merge.

Follow-Up Tasks:

1. Connect the settings depending on what the user selects with its corresponding interview.
2. Design and make the GUI more visually appealing.

Overall Nice work!
