Adding an override for whatwg-url to remove Node's DeprecationWarning about punycode

[RobinCsl]

Hello Scott,

Just going through the replay of your workshop and cloned the repo, managed to get things running.

With Node.js v22.7.0, I got a warning in the console, which makes the output less nice to read:

$ NODE_OPTIONS="--trace-deprecation" npm start "hello, my name is Smith"

> start
> npx tsx index.ts hello, my name is Smith

(node:227918) [DEP0040] DeprecationWarning: The `punycode` module is deprecated. Please use a userland alternative instead.

Hello, Smith! How can I assist you today?

You might want to consider adding this overrides in the package.json file to make the warning go away (after another npm install)

"overrides": {
  "whatwg-url": "13.0.0"
}

Got this solution from openai/openai-node#527 (comment) and it works fine for me.

All the best.
