Add generate_team.py script that reads .all-contributorsrc and generates
the team.md page automatically. This keeps the website team page in sync
with the README contributors.
- Add tinytorch/site/scripts/generate_team.py
- Update both deploy workflows to run the script before building
- Contributors added via @all-contributors now appear on the website
The script runs during site build, so team.md stays fresh with each deploy.
