Bug: distributing `types.ts` makes it checked by TypeScript, which might find unfixable problems

What did you do?

Hello! Due to distribution of types.ts with this package, TypeScript tries to typecheck it and on certain setups, it might report unfixable type errors.

We have remark@14.0.2 installed as a dependency, which in turn has a dependency "@types/mdast": "^3.0.0".

Probably due to how pnpm places file with shamefully-hoist=true and due to how TypeScript modules resolution works, type-import of mdast from @eslint/markdown resolves to v3 instead of v4 which causes TS compiler to report errors.

My eslint.config.ts:

import eslintPluginMarkdown from '@eslint/markdown';
import { defineConfig } from 'eslint/config';

export default defineConfig({
  files: ['*.md'],
  plugins: {
    markdown: eslintPluginMarkdown,
  },
});

What did you expect to happen?

I expect no type errors which would have not been reported if types.ts file was not distributed, because only .d.ts from node_modules are not checked with TS' "skipLibCheck": true.

What actually happened?

Thanks for the report. This is strange. This should be fixed once we merge #383, so keeping open to verify.
