Unable to import toc and metadata from .mdx when unifiedjs.vscode-mdx in on at VS Code

[MOZGIII]

Describe the bug A clear and concise description of what the bug is.

import Content, { metadata, toc } from "./content.mdx";

shows errors:

Module '"./content.mdx"' has no exported member 'metadata'. Did you mean to use 'import metadata from "./content.mdx"' instead?
Module '"./content.mdx"' has no exported member 'toc'. Did you mean to use 'import toc from "./content.mdx"' instead?

However, when I add the following mdx.d.ts:

declare module "*.mdx" {
  import type { Heading, NextraMetadata } from "nextra";

  let MDXComponent: (props) => JSX.Element;
  export default MDXComponent;

  export const metadata: NextraMetadata;
  export const toc: Heading[];
}

It starts working file for tsc.

In the VS Code though, the unifiedjs.vscode-mdx provides a language server, which does some magic code injections into the evaluation context at which it itself works (see here) - and long shorty short it breaks the types.

This is some hellish interaction, but it should be correctable by passing the right settings to the language server - in particular, the plugins we use to generate those toc and metadata parameters.

To Reproduce Steps to reproduce the behavior:

1. Install VS Code.
2. Install unifiedjs.vscode-mdx extension from the VS Code marketplace.
3. Make some dummy content.mdx file.
4. Make some page.tsx file with (app router) and try importing metadata and toc from that content.mdx like the above.
5. Observer the error in the editor and in tsc.
6. Bring in the mdx.d.ts from above, see the error gone from the tsc but no the editor.

Well, believe it or not, I expected it to just work.
