Add prerequisites and exclude migration notebooks from CI/CD tests

- Add sentence-transformers and numpy as explicit prerequisites in both migration notebooks
- Add migration notebooks to .github/ignore-notebooks.txt to skip CI/CD testing
- These notebooks require additional dependencies (sentence-transformers, numpy) not available in test environment
- Notebooks are designed for interactive use with proper dependency installation
