adds a font example to demonstrate why commonjs is needed

I was getting an error that vite could not understand 'require':

ReferenceError: require is not defined

However when you add the commonjs plugin it works:

import { defineConfig } from 'vite';
import commonjs from 'vite-plugin-commonjs';
export default defineConfig({
  plugins: [commonjs()],
});

I added this because this is the recommended way to handle fonts for the web with expo-font you can include fonts in the bundle for mobile, but it won't work on the web since there's really no equivalent.

this is resolved by storybookjs/storybook#30305, and when that's merged this PR isn't needed
