📚 Description

This PR adds and addtionnal check when using nuxt content with nuxthub.

In cases when nuxt content is after nuxthub and nuxthub doesn't have databse enabled, deploying on nuxthub won't update the DB. Because the modification brought to nuxt.options.hub done too late.

export default defineNuxtConfig({
  modules: [
    '@nuxthub/core', // nuxt content should load before nuxthub or the user should enable databse themselves
    "@nuxt/content",
  ]
})
