React 19 support

[kossnocorp]

Hey! Thank you so much for this helpful library 🙏

There's a small problem, though. After upgrading to React 19, released a few days ago, it started breaking as it locks on React 18. I tested it on my project with React 19 by copying the source of vitest-browser-react code into my repo, as there's no need for any changes. It just works. I think you can safely expand the dependency version to include 19 and ship it as a new version.

Shouldn't "react": ">18.0.0" cover react 19?

I agree with @sheremet-va here, we have `"react": ">18.0.0" which allows these versions (taken from semver.npmjs.com):

Confirming that I can use this pkg with React 19; see xeger/locatorium#1 for proof.

On my initial attempt, I experienced an odd error about react-dom/client lacking a default export, or not exporting something. I created the project with React 18, which fixed the issue, and later I upgraded to React 19; the issue did not occur.

I've encountered this error intermittently in the past, not always with React 19. I haven't bothered to investigate, as I'm not sure whether it's a legitimate issue with a package or some issue with transpiler/bundler configuration. I have only seen it happen when using npm as a package manager, never with pnpm.
