chore: Add initial files for VS Code web integration

[Harsh-Microsoft]

Purpose

This pull request introduces a new infra/vscode_web directory that provides templates and supporting files for deploying Azure AI Foundry projects directly from VS Code for the Web. It includes example code samples, environment configuration, installation scripts, and documentation to help users quickly get started with both connection string and endpoint authentication methods. Additionally, the PR updates the main README.md to add a launch badge for Visual Studio Code Web.

New Azure AI Foundry template assets:

• Added a comprehensive set of template files under infra/vscode_web, including Python code samples (codeSample.py, endpointCodeSample.py), environment configuration (.env), installation script (install.sh), and documentation (README.md, README-noazd.md). These assets support quick deployment and usage of Azure AI Foundry from VS Code for the Web. [1] [2] [3] [4] [5] [6]
• Added dependency files for both connection string and endpoint authentication methods (requirements.txt, endpoint-requirements.txt).
• Provided a .gitignore tailored for Python, .NET, Java, and general development environments.
• Included an MIT license for the new template assets.

Integration and discoverability:

• Added an index.json manifest to describe the available templates and their assets for both authentication methods, improving discoverability and integration with tooling.

Documentation improvements:

• Updated the main README.md to add a badge and link for launching the solution in Visual Studio Code Web, alongside existing badges for Codespaces and Dev Containers.
