FED-3926 Add non-minified React 18 prod bundle

[sydneyjodon-wk]

Based on this support request, we should add a non-minified version of our React 18 prod JS bundle

Changes

• Add non-minified react.js prod bundle
• Add tests

QA instructions

• CI passes
• New tests are sufficient test coverage
• New react.js bundle is non-minified

Failing CI on Dart 3 is also happening in master #420 - looking into this separately

One comment; this results in non-react code, like react-redux and react-dart JS, not being minified, but unfortunately doesn't seem to affect React code.

That might be worth moving forward with, but I feel it might not provide too much value to consumers. 🤷 Thoughts?

Otherwise, all the changes look good!

I was diffing this file to a formatted version of react.min.js locally, and noticed that almost all the code from React is still minified. See that diff here: https://gist.github.com/greglittlefield-wf/f3c45e0f1769170344e50266f617c479

I did a little digging, and I think it's because React pre-minifies their production bundle 😕, both for

• react:
  • https://github.com/facebook/react/blob/v18.2.0/packages/react/npm/index.js#L3-L7
• react-dom
  • https://github.com/facebook/react/blob/v18.2.0/packages/react-dom/npm/index.js#L31-L38

So we might not be able to have non-minified code and production behavior at the same time after all ☹️
