What problem does this feature solve?

Configuring rust plugins and js plugins in farm.config.ts uses different methods currently, for example:

import farmSassPlugin from '@farmfe/js-plugins-sass';

export default defineConfig({
  plugins: [
    // rust plugin
    ['@farmfe/plugin-react', {}], 
    // js plugin
    farmSassPlugin({
      // globals: ['./src/variables.scss']
    })
  ],
});

Farm uses @farmfe/plugin-react to configure rust plugins and uses farmSassPlugin({}) to configure js plugins. It's in consistent and it's hard to add types for rust plugin options.

we need to normalize this 2 methods.

What does the proposed API look like?

import react from '@farmfe/plugin-react';
import farmSassPlugin from '@farmfe/js-plugins-sass';

export default defineConfig({
  plugins: [
    react({}),
    farmSassPlugin({
      // globals: ['./src/variables.scss']
    })
  ],
});

using new react({}) strategy to configuring rust plugin, and keep the old ways compatible.
