Fix CI workflow: use catthehacker/ubuntu:act-latest for Node.js support

The actions/checkout@v4 action requires Node.js, but python:3.12-slim doesn't include it.
Using catthehacker/ubuntu:act-latest which has both Node.js and Python support.

- Update ci.yaml to use act-compatible image
- Update deploy.yaml to use act-compatible image
- Use actions/setup-python@v5 for Python installation
