Pin Docusaurus packages to ~3.9.0 to avoid webpack incompatibility (meta-pytorch#3268)

Summary:
- Changed `^3.9.0` to `~3.9.0` for all four Docusaurus packages (`docusaurus/core`, `docusaurus/preset-classic`, `docusaurus/module-type-aliases`, `docusaurus/types`).
- This allows patch updates (3.9.x) but prevents the jump to 3.10.0 where a webpack/webpackbar incompatibility exists.
- Docusaurus 3.10 (via webpackbar) passes deprecated options (`name`, `color`, `reporters`, `reporter`) to webpack's `ProgressPlugin`, which webpack 5.99+ rejects. Once Docusaurus fixes this upstream, we can switch back to `^3.10.x` or later.

Pull Request resolved: meta-pytorch#3268

Test Plan: - [ ] Verify website builds successfully with `npm run build` in the `website/` directory.
