Describe the bug

Cannot set the titleTemplate as a function (used for default titles when non existent).

Example:

import { defineNuxtConfig } from 'nuxt'

// https://v3.nuxtjs.org/api/configuration/nuxt.config
export default defineNuxtConfig({
    app: {
        head: {
            titleTemplate: (titleChunk) => {
                return titleChunk ? `${titleChunk} - Site Title` : 'Site Title';
            },
        }
    }
})

Additional context

As far as I know, Nuxt 3 uses vue-meta, which the docs show it supports: https://vue-meta.nuxtjs.org/api/#titletemplate
