Add missing jest-junit dependency to node-renderer package

The CI script for react-on-rails-pro-node-renderer was failing because
jest-junit was not installed as a devDependency, even though the CI
script referenced it as a reporter.

Changes:
- Add jest-junit ^16.0.0 to devDependencies in node-renderer package.json
- Add junit.xml to .gitignore (test output file)

Fixes CI error:
  Error: Could not resolve a module for a custom reporter.
  Module name: jest-junit
