Installation guide for Astro

Describe the feature

I was struggling to get Formkit to work in Astro.build. The docs only explain for Vue and Nuxt. Ended up getting it to work, so for the people also struggling:

astro.config.mjs

import { defineConfig } from 'astro/config';
import vue from '@astrojs/vue';

export default defineConfig({
  integrations: [
    vue({ appEntrypoint: '/src/pages/_app' })
  ],

src/pages/_app.ts

import type { App } from 'vue';
import { plugin, defaultConfig } from '@formkit/vue'

export default (app: App) => {
    app.use(plugin, defaultConfig);
}

Since Astro is quiet popular and getting more fans every day, I think it would be great to add it to the docs. Especially since a lot of Astro users come from tools like 11ty, hugo and Jekyll, not vue.

We added a section in the intallation guide on how to integrate Astro and Formkit.

Closing as the documentation now has the Astro integration.
