Describe the Bug

seems next 12.2.3 do now validates next.config.js with ajv (https://github.com/vercel/next.js/pull/38498).

As I’m using vercel analytics on my non-vercel deployments, I need to hand in the analyticsId property to next.config.js.

/**
 * @type {import('next').NextConfig}
 **/
const config = {
  trailingSlash: false, // disable trailing slashes.
  poweredByHeader: false, // disable powered by header.
  reactStrictMode: true, // set strict mode for react.
  swcMinify: true, // minify using swc/rust.
  compress: false, // let nginx handle compression.
  analyticsId: "MY_ANALYTICS_ID", // vercel analytics id.

and at the very startup next 12.2.3 now warns about the analyticsId property:

warn  - Invalid next.config.js options detected:
[
  {
    "instancePath": "",
    "schemaPath": "#/additionalProperties",
    "keyword": "additionalProperties",
    "params": {
      "additionalProperty": "analyticsId"
    },
    "message": "must NOT have additional properties"
  }
]
See more info here: https://nextjs.org/docs/messages/invalid-next-config

Expected Behavior

allow analyticsId property without a warning.

Getting this same error when using next-pwa! In this case, the additionalProprty it doesn’t like is "pwa"
