ci: add node_modules/.bin to PATH in init actions

Why:
pkglab is a devDependency installed by pnpm, but CI workflow steps
couldn't find it because node_modules/.bin isn't in PATH by default.
Integration tests that run pkglab from temp directories outside the
repo also need it accessible without pnpm exec.
