Include Example Data for Quick Testing

Description: Add a sample data file that contains example information for all sections (e.g., name, contact details, education, work experience). This will help users quickly test the template without having to fill out their own information initially.

Start by inspecting the repository's TeX template and any existing example or sample-data conventions. Add an example data file covering the named resume sections, then verify that users can use it to test the template without entering their own information.
