Resume button not work properly

When I click resume-> button it redirect me to github. that's not a good idea. The purpose of the buton is to download our resume/cv

No file or test is named in the issue. Start by locating the Resume button in the portfolio template and reproduce its current redirect behavior; update the relevant entry point so the button downloads the resume/CV instead of opening GitHub, then verify the browser download behavior.
