cleanup/refactory: Implement and refactor e2e tests for 'alpha generate' command

- Added comprehensive end-to-end tests for the 'generate' command.
- Ensured proper validation of the 'PROJECT' file after project initialization and regeneration.
- Verified correct handling of multigroup layouts, Grafana, and DeployImage plugins.
- Refactored the test structure to align with existing patterns used in other tests.
- Improved maintainability and test coverage to support future growth and more scenarios.
- Improve coverage to ensure more case scenarios
