Problem
CI currently installs a custom build of sbuild from eth-pkg/sbuild-ubuntu releases. We should migrate to using the stock Debian/Ubuntu sbuild package instead.
Solution
Update .github/actions/setup-sbuild/action.yml to install sbuild directly via apt instead of downloading custom .deb files from GitHub releases.
