Fix Debian container: install basic tools before checkout

- Add step to install git, curl, wget, ca-certificates in Debian container
- This fixes the 'git: not found' error from run #20
- Debian container needs basic tools installed before checkout step
- Install tools before attempting to clone repository

The Debian container is minimal and doesn't include git by default,
causing the checkout step to fail with 'command not found' error.
