fix: Add platform-specific setup and bash shell to test-python-examples

- Add conditional Java setup for macOS/Windows (Docker not available)
- Add conditional Docker Buildx setup for Linux only
- Force bash shell on all run steps (fixes PowerShell syntax errors on Windows)
- Matches setup pattern from test-python-bindings.yml
