Chore/react 18 create root

[tomanagle]

• Updates the react & react-ts frontends to use createRoot instead of ReactDOM.render as ReactDOM.render is no longer supported in React 18

Looks good 😄

Thanks for doing this! Is there any chance you could add them to the directories under generate? My fear is they'll get overwritten next time we generate the templates again. It should be fairly obvious what's happening in the generate directory (those files are copied after a default vite generation) but if you need more info, I'm happy to help! 🙏

Yup, I'll take a look around and update the PR :)

I updated those templates (hopefully in the right place).

Also realised my linter was changing more lines than required, so fixed that up too
