feat(nuxt): Introduce getAuth() helper

[wobsoriano]

Description

This PR introduces a getAuth() helper to our Nuxt SDK similar to our other SDKs (Next.js) that retrieves the current auth state.

Example:

import { getAuth } from '@clerk/nuxt/server';

export default eventHandler((event) => {
  const { userId } = getAuth(event);

  if (!userId) {
    // User is not authenticated
  }
});

Resolves ECO-405
