Refine GitHub Actions workflow for Cypress testing

- Updated the logic for generating test groups to use 'find' instead of 'ls' for improved accuracy in locating directories.
- Enhanced the fallback condition to handle cases where the generated groups are empty or not found, ensuring a default group is always available.
- Improved logging to provide clearer output regarding the generated test groups.

This update enhances the reliability of the CI process by ensuring proper detection and handling of test groups.
