Open sourcing our microfrontend React bridge

I wrote previously about how we upgraded React incrementally across multiple micro-frontends using a bridge component. We initially looked to use the @module-federation/bridge-react package, but ran into some issues with re-rendering and it doing more than we needed.

To solve this we created our own package, which we're using successfully in production to allow our 28 micro-frontends to upgrade React independently. We've now open sourced this package as @mintel/mfe-react-bridge on npm.

It's a small library with a couple helper functions to provide a React component interface to render micro-frontends that use different React versions (or totally different UI frameworks). It provides TypeScript types, supports React 17 and 18+, and is well-tested.

Hopefully this proves useful to others facing similar challenges with micro-frontends and React versioning. Feel free to raise any issues on GitHub.
