Support Local dev experience for API Management backend

**Is your feature request related to a problem? Please describe.**
I have successfully linked an endpoint in API management. But there is no documentation or example to help me develop the frontend and backend together in a local environment.

**Describe the solution you'd like**

A way to help me to proxy `/api` calls into an API management endpoint. Currently, there is a big gap between this documentation: https://learn.microsoft.com/en-us/azure/static-web-apps/apis-api-management and the ability to successfully develop locally against the management API. I wish to see clear documentation about each place:
- What should my CLI command look like?
- What should my saw-cli.config.json look like?
- What should the `fetch()` call look like?
- What should the API management settings look like?

In addition, are there ways to cURL or Postman against my endpoint? I think that is the bare minimum to get backend development inner loop started.

Commencez par la documentation Azure API Management liée et par le flux de proxy local `/api` demandé. Documentez la commande CLI, `saw-cli.config.json`, l’appel à `fetch()`, les paramètres d’API Management, ainsi que toutes les étapes avec cURL ou Postman nécessaires au développement local du frontend/backend. Le travail est considéré comme terminé lorsqu’une personne débutante peut suivre l’exemple de bout en bout avec la management API.
