feat: add createModuleFederationConfig helper

[tonoizer]

This PR adds createModuleFederationConfig helper for Vite config DX to further follow more the module federation recommendations to use the module-federation.config.tsfile structure (https://module-federation.io/guide/build-plugins/plugins-rspack.html#create)

createModuleFederationConfig(options) => options

The goal is DX consistency with the official Module Federation integrations for Rspack, Rsbuild, and Rspress, where users are encouraged to define their federation config in a dedicated module-federation.config.ts file and pass that object into the bundler plugin.

Why

• Aligns Vite with the existing Module Federation config-file convention.
• Gives users a simple, typed entry point for module-federation.config.ts.
• Improves discoverability and keeps docs/examples consistent across bundlers.
• Keeps Vite-specific typing by using @module-federation/vite's own ModuleFederationOptions type instead of the generic SDK plugin type.

Example

// module-federation.config.ts
import { createModuleFederationConfig } from '@module-federation/vite';

export default createModuleFederationConfig({
  name: 'remote_a',
  exposes: {
    './Feature': './src/Feature.tsx',
  },
});

// vite.config.ts
import { defineConfig } from 'vite';
import { federation } from '@module-federation/vite';
import moduleFederationConfig from './module-federation.config';

export default defineConfig({
  plugins: [federation(moduleFederationConfig)],
});
