Update dependencies

[alexshoe]

• Updates dependencies inpackages.json, skipping over react, react-docgen, and react-dom
• Re-installed to update sub-dependencies in node_modules and package-lock.json
• Fixes various dependency issues and some existing syntax errors.

I have rebuilt and run usage.py, usage-method.py, and usage-advanced.py - everything works as expected.
