Type error for flat configs with typescript-eslint's .config helper

[drasern]

Describe the bug
A type error is thrown when using the typescript-eslint config() helper function to provide type checking for the "flat/recommended" config.

The code:

import tseslint from "typescript-eslint";
import storybook from "eslint-plugin-storybook";

export default tseslint.config(
  ...storybook.configs["flat/recommended"],
);

Versions:

    "eslint-plugin-storybook": "^0.11.0",
    "eslint": "^9.14.0",
    "typescript": "^5.6.3",
    "typescript-eslint": "^8.14.0",

The error:

Argument type
{name: string, plugins: {readonly storybook: any}, files?: undefined, rules?: undefined} | {name: string, files: string[], rules: {"react-hooks/rules-of-hooks": string, "import/no-anonymous-default-export": string, "storybook/await-interactions": string, "storybook/context-in-play-function": string, "storybook/default-exports": string, "storybook/hierarchy-separator": string, "storybook/no-redundant-story-name": string, "storybook/prefer-pascal-case": string, "storybook/story-exports": string, "storybook/use-storybook-expect": string, "storybook/use-storybook-testing-library": string, ...}, plugins?: undefined} | {name: string, files: string[], rules: {"storybook/no-uninstalled-addons": string, "react-hooks/rules-of-hooks"?: undefined, "import/no-anonymous-default-export"?: undefined, "storybook/await-interactions"?: undefined, "storybook/context-in-play-function"?: undefined, "storybook/default-exports"?: undefined, "storybook/hierarchy-separator"?: undefined, "storybook/no-redundant-story-name"?: undefined, "storybook/prefer-pascal-case"?: undefined, "storybook/story-exports"?: undefined, "storybook/use-storybook-expect"?: undefined, ...}, plugins?: undefined}
is not assignable to parameter type ConfigWithExtends ...   Type string is not assignable to type
Record<string, 0 | 1 | 2 | "error" | "off" | "warn" | [0 | 1 | 2 | "error" | "off" | "warn", ...unknown[]]>[string] | undefined
     Type string is not assignable to type
0 | 1 | 2 | "error" | "off" | "warn" | [0 | 1 | 2 | "error" | "off" | "warn", ...unknown[]]

This is because the declared type for each rule is the wide string instead of the more specific "error" | "off" | "warn" that the config is expecting.

To Reproduce
Steps to reproduce the behavior:

1. Install eslint-plugin-storybook and typescript-eslint
2. Wrap your esling.config.js in the config() helper function
3. See error

Expected behavior
The declared type should match the acceptible possible values for the rules.

Additional context
The actual values of the strings in the config are correct, but the type definition file is widened to string.
