feat(deps): update to eslint 9

[acomanescu]

BREAKING CHANGE: will not work with eslint 8 due to flat config format

Usage:

const nodeConfig = require('@vercel/style-guide/eslint/node');
const typescriptConfig = require('@vercel/style-guide/eslint/typescript');
const browserConfig = require('@vercel/style-guide/eslint/browser');
const reactConfig = require('@vercel/style-guide/eslint/react');
const nextConfig = require('@vercel/style-guide/eslint/next');
// ... other config files

module.exports = [
  ...nodeConfig,
  ...typescriptConfig,
  ...browserConfig,
  ...reactConfig,
  ...nextConfig,
  {
    languageOptions: {
      parserOptions: {
        project: './tsconfig.json', // if you need TS support
      },
    },
    settings: {
      'import/resolver': {
        typescript: {
          project: './tsconfig.json',  // if you need TS support
        },
      },
    },
    rules: {
      // ... rule overrides
    },
  }
];

GREAT timing. Maintenance on turborepo is blocked on needing ESLint 9, so I'll definitely be doing my best to help get this reviewed and merged. Thank you for the PR and stay posted.

[acomanescu]

Hi @dimitropoulos, is there anything I can do to help having this merged?

[yadokarization]

Hi @dimitropoulos, just checking in to see if there's an update on the review process. I'm very much looking forward to this being merged.

[DrPye]

@dimitropoulos any update on this, this is literally the only package that is stopping us from using next 15!

[yadokarization]

Hi @mrmckeb, are there any plans to maintain this repository? It seems that several PRs are pending review without any progress.
This package is really useful for us. Thanks!

[dimitropoulos]

hi everyone! sorry. things move so fast here at Vercel, wow! I'll take a look at this in the coming week and see what we can do. Internal priorities regarding ESLint in general don't directly align with this, but hey, that's no reason not to help the community - and that's exactly what I still hope to do.

[gnify]

Hey, no-floating-decimal and new-parens are deprecated since ESLint v8.53.0. ESLint's team moved them to @stylistic/eslint-plugin-js. Can we move to the alternatives suggested in the docs?

UPD: Also eslint-plugin-vitest is no longer maintained because the original maintainer has lost access to their npm account. @vitest/eslint-plugin should be used for all the latest features.
