Sorry for the delay, I started a new job recently. You have to update the source field to take into account the locale dynamic param:

/** @type {import('next').NextConfig} */
const nextConfig = {
  async rewrites() {
    return [
      {
        source: "/:locale/blog",
        destination: "https://example.com/blog",
      },
      {
        source: "/:locale/blog/:slug",
        destination: "https://example.com/blog/:slug", // Matched parameters can be used in the destination
      },
    ];
  },
};

I've tested it here and it's working as expected when navigating to /en/blog or /blog directly.
