[Doc Issue] Quickstart: Deploy your first hosted agent - Microsoft Foundry | Microsoft Learn needs to be updated

azd version 1.23.6 (commit 16c72e70630dd9b078f457902b04e9ddac736ec8)

Walking through [Quickstart: Deploy your first hosted agent - Microsoft Foundry | Microsoft Learn](https://learn.microsoft.com/en-us/azure/ai-foundry/agents/quickstarts/quickstart-hosted-agent?view=foundry)

1. Pre-req - "[Microsoft Foundry project](https://learn.microsoft.com/en-us/azure/ai-foundry/tutorials/quickstart-create-foundry-resources?view=foundry)" should be removed. I assumed I need to create a project manually before I start but a new project is actually created for me.
2. PowerShell Invoke-RestMethod hides nested response content — It displayed System.Object[] instead of the actual agent output. Fix: pipe through .output.content | ConvertTo-Json -Depth 5 to expand the nested objects and see the full text response. Recommend using this instead:
```
(Invoke-RestMethod -Method Post -Uri "http://localhost:8088/responses" -ContentType "application/json" -Body '{"input":"What is Microsoft Foundry?"}').output.content | ConvertTo-Json -Depth 5
```
