Describe the Bug

When I run $ pnpm create next-app@latest --experimental-app --example cms-strapi cms-strapi-app I do not see an app/ directory

Expected Behavior

When I run $ pnpm create next-app@latest --experimental-app --example cms-strapi cms-strapi-app I am expecting an app/ directory and next.config.js to have the appropriate flag:

/** @type {import('next').NextConfig} */
const nextConfig = {
  experimental: {
    appDir: true,
  },
};

To Reproduce

Run $ pnpm create next-app@latest --experimental-app --example cms-strapi cms-strapi-app
