fix: Update deployment workflow to push built files to master branch

- Changed from GitHub Pages API deployment to git push to master
- This maintains compatibility with existing GitHub Pages configuration
- Workflow now builds site on publish branch and pushes static files to master
- Simulates the original Travis CI deployment behavior
