Convert quickstart to Node Typescript

The current repo is described in the readme.

I want to convert this to all our supported languages, starting with Node and Typescript.

Please convert in a new branch.

Some considerations:
- use the Typescript v4 programming model
- Use as much as the /infra/* bicep as possible, and always prefer using AVM
- Please use this repo as a reference of what Typescript quickstarts should look like: https://github.com/Azure-Samples/functions-quickstart-typescript-azd
- Use latest functions extension bundles, because there is no NPM (or NuGet equivalent) for Typescript functions.
- Please baseline on Node version 22.x
