feat(ci.yaml): add npm publish dry-run step

This commit adds a new step in the GitHub Actions workflow for
performing a dry-run of npm publish. This is to ensure that the
npm package is ready for publishing. The Node.js version used is
20.x. The deno.lock file has also been updated to include a new
dependency.
