Migrate examples to tests_e2e directory structure

- Relocated all files and scripts from `examples` to `tests_e2e` for better organization.
- Updated references and paths in configurations, scripts, and test files.
- Adjusted `bump-version.sh` to handle the new `tests_e2e` structure.
- Updated `.gitignore` to reflect path changes.
