fix(create-vite): revert eslint 9 upgrade in templates

[patak-dev]

Description

Partial revert of #16661, we shouldn't yet update eslint to v9 in the templates because eslint-plugin-react doesn't yet support it.

We're keeping track of the upgrade to v9 in templates here:

• feat(create-vite): add eslint.config.js to React templates #12860

Thanks!

I would recommend to use https://www.npmjs.com/package/@eslint/compat#fixing-plugins to fixup the react plugin. From my perspective, I see the react plugin probably won't support ESLint v9 for a long while, which shouldn't be the reason for blocking the ecosystem. ESLint team has put effort to have a compact layer and we should help to move the ecosystem forward

@antfu I think that is a good idea. I'll go ahead and merge this PR because vite.new/react is issuing a lot of warnings. I would support us helping eslint v9 get more adoption, let's discuss that in a future PR.

[ArnaudBarre]

Yeah I mentioned in #12860 that I think adding the compat is better than waiting, I'll take the PR over to release it

The original one should be updated now
