fix: get react file-upload example working with vite

[travis]

create-react-app projects don't have the proper loaders to handle loading typescript in dependencies. vite is used in our other examples so it makes sense to me that we'd use it for react as well.

putting this in a separate PR before I update all the other examples to get feedback before committing to this approach, and to avoid too many merge conflicts with the efforts underway to update examples by @cmunns and @natevw

LGTM, only question is does it make it more confusing for beginners to get hacking on it? Probably it's fine

Overall looks good to me too. +1 on giving the JSX files an actual .jsx extension, and cleaning up the public folder.

I don't think this will cause me much grief merging with my changes on #204, although it might be worth discussing the plan for all the other examples — I'm happy to merge this as a smaller trial run but otoh I don't see a big reason not to just plow forward with similar changes on all examples at once?

ok amazing - @alanshaw I'd like your signoff before I convert the rest of the examples to vite - happy to add that to this PR if we're all aligned

I don't think so honestly - tbh I would never recommend create-react-app to beginners these days, and we already use vite for all the other examples.

👍 happy to use newer and better tooling and it's nice to have consistency with other examples anyway.
