Update .gitignore to exclude additional directories

- Added 'exps/' and 'summary/' directories to the .gitignore file to prevent tracking of experimental and summary data.
- Retained existing exclusion for 'data/' while removing the specific exclusion for 'data/*' to allow for potential subdirectory tracking.
