Migrate to tsdown to fix dts output

[lishaduck]

Current dts:

import * as tsEslintParser from '@typescript-eslint/parser';
import { ParserOptions } from '@typescript-eslint/parser';

var name = "typescript-eslint-parser-for-extra-files"; // ← invalid
var version = "0.7.0";

declare const meta_name: typeof name;
declare const meta_version: typeof version;
declare namespace meta {
  export { meta_name as name, meta_version as version };
}

declare function parseForESLint(code: string, options?: ParserOptions): ReturnType<typeof tsEslintParser.parseForESLint>;

export { meta, name, parseForESLint };

New dts:

import * as tsEslintParser from "@typescript-eslint/parser";
import { ParserOptions } from "@typescript-eslint/parser";
import { TSESLint } from "@typescript-eslint/utils";

//#region src/meta.d.ts
declare const meta: TSESLint.FlatConfig.PluginMeta;
declare const name: string;

//#endregion
//#region src/index.d.ts
declare function parseForESLint(code: string, options?: ParserOptions): ReturnType<typeof tsEslintParser.parseForESLint>;

//#endregion
export { meta, name, parseForESLint };
