##### Major Changes

-
[`4642a86`](https://redirect.github.com/fuma-nama/fumadocs/commit/4642a86):
**Remove `typescriptGenerator` from `fumadocs-docgen`**

**why:** Move dedicated parts to `fumadocs-typescript`, so all docs
generation features for TypeScript can be put together in a single
module.

**migrate:** Use `fumadocs-typescript` We made a new
`remarkAutoTypeTable` remark plugin generating the type table but with a
different syntax:

    ```mdx
    <auto-type-table path="./my-file.ts" name="MyInterface" />
    ```

    Instead of:

    ````mdx
    ```json doc-gen:typescript
    {
      "file": "./my-file.ts",
      "name": "MyInterface"
    }
    ```
    ````

-
[`4642a86`](https://redirect.github.com/fuma-nama/fumadocs/commit/4642a86):
**Move `remarkTypeScriptToJavaScript` plugin to
`fumadocs-docgen/remark-ts2js`.**

    **why:** Fix existing problems with `oxc-transform`.

    **migrate:**

    Import it like:

    ```ts
import { remarkTypeScriptToJavaScript } from
'fumadocs-docgen/remark-ts2js';
    ```

    instead of importing from `fumadocs-docgen`.
