Issue: "This application can't be opened" error was encountered on using the tabcmd.app on Mac environment from release artifacts

Resolution: The app wasn't properly bundled and the zip of the bundle associated with actions/upload-artifact@v4 github action led to loss of executable file's +x permission and eventually led to aforementioned error while using the app. This PR addresses this issue by tar-ing the app bundle before uploading it to artifact thereby preserving the necessary file permissions
