chore: update typescript-eslint configs

[hyunbinseo]

Fixes #12720

Used the config() helper function. An exported type can be used as well:

https://typescript-eslint.io/packages/typescript-eslint#config

// eslint.config.mjs
// @ts-check

import eslint from '@eslint/js';
import tseslint from 'typescript-eslint';

/** @type {import('@typescript-eslint/utils').TSESLint.FlatConfig.ConfigFile} */
export default [
  eslint.configs.recommended,
  ...tseslint.configs.recommended,
  {
    /*... */
  },
  // ...
];

• Ideally, include a test that fails without this PR but passes with it.

Tests

• Run the tests with pnpm test and lint the project with pnpm lint and pnpm check

Changesets

• If your PR makes a change that should be noted in one or more packages' changelogs, generate a changeset by running pnpm changeset and following the prompts. Changesets that add features should be minor and those that fix bugs should be patch. Please prefix changeset messages with feat:, fix:, or chore:.
