refactor: remove redundant GitHub sync functionality

- Remove 'Push to GitHub' sync button from Workbench
- Clean up unused parameters and imports
- Improve UX by using only the proper GitHub deployment feature
- Fix ESLint and Prettier formatting issues
- Fix unused variable in GitHubDeploymentDialog

This removes the old sync functionality in favor of the comprehensive
GitHub deployment feature that builds projects before deployment.
