[JS] [Next.js] Webpack Console Warnings for googleCloud plugin

[MichaelDoyle]

Describe the bug

Init a new next.js project using the genkit CLI. Then add the googleCloud plugin and enable telemetry.

 ⚠ ./node_modules/@opentelemetry/instrumentation-winston/build/src/instrumentation.js
Module not found: Can't resolve '@opentelemetry/winston-transport' in '/Users/michaeldoyle/repos/thirdparty/nextjs/node_modules/@opentelemetry/instrumentation-winston/build/src'

Import trace for requested module:

Module not found: Can't resolve '@opentelemetry/exporter-jaeger' in '/Users/michaeldoyle/repos/thirdparty/nextjs/node_modules/@opentelemetry/sdk-node/build/src'

Similar to #928, the workaround is to install and/or externalize the dependencies.

/** @type {import('next').NextConfig} */
const nextConfig = {
  experimental: {
    serverComponentsExternalPackages: [
      "@opentelemetry/sdk-node",
      "@opentelemetry/winston-transport",
    ],
  },
};

export default nextConfig;

Runtime (please complete the following information):

Node: 20.17.0
Genkit: 0.5.13
Next: 14.2.12

** Node version**

v20.17.0
