Add AI Discord and GitHub Community Links to README

[Copilot]

This PR adds Azure AI Foundry community links to the README to help users get support and connect with the AI developer community.

Changes

1. Added Discord Badge to Header

A new Discord badge has been added to the badges section at the top of the README, positioned right after the GitHub Codespaces badge. This makes it easy for users to quickly find and join the Azure AI community Discord server.

[![Join Azure AI Foundry Discord](https://img.shields.io/badge/Discord-Azure_AI_Community-blue?style=flat-square&logo=discord&color=5865f2&logoColor=fff)](https://aka.ms/foundry/discord)

The badge uses the same flat-square style as the existing badges to maintain visual consistency.

2. Added "Getting Help" Section

A new dedicated section has been added between "Troubleshooting" and "Contributing" to provide users with clear paths for getting help when building AI applications. This section includes:

• Azure AI Foundry Discord: For community support, questions, and discussions about building AI apps
• Azure AI Foundry Developer Forum: For product feedback and reporting issues encountered while building

Both links use prominent for-the-badge style badges to make them stand out and easy to find.

Why These Changes?

These additions make it easier for developers working with serverless AI applications to:

• Connect with the Azure AI developer community
• Get help when stuck on implementation issues
• Provide feedback to improve Azure AI services
• Learn from other developers building similar applications

The links complement the existing "Troubleshooting" section by providing community-driven support options beyond the troubleshooting guide.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• functionscdn.azureedge.net
  • Triggering command: node lib/install.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Plan

Locate the README.md file in the root of the project and add the following content at the bottom of the file if "Getting Help" section and the links do not already exist in the README.md file. If the README.md file already contains a section for AI Discord or the Azure AI Foundry Developer Form, do not add the links again.

RULES:

• ONLY MODIFY the README.md file at the root of the repository. DO NOT MODIFY any other files.
• If the "Getting Help" section does not already exists, add it to the bottom of the README.md, but before "Contributing" and "Trademarks" section if they exists at the bottom.
• If there's a badges section in the README.md that do not already include an "AI Community", "Discord" or "AI Discord" (or similar):
  • also add this badge after the Codespaces one (if applicable) [![Join Azure AI Foundry Discord](https://img.shields.io/badge/Discord-Azure_AI_Community-blue?style=flat-square&logo=discord&color=5865f2&logoColor=fff)](https://aka.ms/foundry/discord)
  • if needed, adapt the badge styling to match the other existing badges
