👷 ci: Update build-and-release workflow for DMG creation process

Refactor the DMG creation steps in the GitHub Actions workflow.
Move the app to a temporary directory for better organization and
create a symbolic link to the Applications folder. This improves
the clarity and structure of the build process.
