Removing the `vitepress-plugin-llms` plugin

[okineadev]

Hello, I support translations into different languages and that's great, but I see that you added vitepress-plugin-llms, but unfortunately it doesn't make sense, because LLM doesn't need documentation in different languages and only English is enough for it, besides, English documentation is fresher because it takes more time to translate into other languages

So I ask you to remove this plugin
