Context specific readme

[chidozieononiwu]

What does this PR do?

• Updates Pack-Nuget.ps1 so that it selects Azure or Microsoft Logo based on the MCP.Server PackageId
• Adds a MERGED.md (will eventually become README.md)
• The goal is to have one shared readme to which we can remove or insert content based on the target package type npm|nuget|vsix

GitHub issue number?

#475

[Copilot]

Pull Request Overview

This PR implements context-specific README generation for different package types (npm, nuget, vsix) by introducing a unified template system with conditional content rendering based on the target package. It also updates the NuGet packaging script to dynamically select appropriate logos based on the package ID prefix.

• Adds a comprehensive MERGED.md template with annotation-based content filtering
• Creates a PowerShell script to process README templates and generate package-specific outputs
• Updates NuGet packaging to use Microsoft or Azure logos based on package ID prefix

The intro will read better with below text:

Seamlessly connect AI agents with Azure services directly from Visual Studio Code.

The Azure MCP Server extension implements the MCP specification, bringing all Azure MCP tools together in a single, unified server. Use it on its own or pair it with the GitHub Copilot for Azure extension to unlock richer AI-powered development experiences in supported IDEs.

Remove unneccessary whitespace below:
Further, pre-requisite section, isn't helpful here, can be removed.

---

Further, under Configuration section,
Recommending VS code or some other IDE is redundant here. It should just mention about installing the extension and then remove config section and move this under Installation section only.

@weshaggard @hallipr @KarishmaGhiya @chidozieononiwu - this really complicated the README.md...

I wish we merged #578 before this. I think your formatting is about to need to be re-reviewed for each package
