Add Claude Code plugin installation instructions to Azure MCP Server README (#3003)

* Add Claude Code plugin installation instructions to Azure MCP Server README

Adds instructions for installing the Azure plugin into Claude Code from
Anthropic's official claude-plugins-official marketplace, which no longer
requires adding a custom marketplace. Updates the top-level README badge,
the Client-Specific Configuration table, and the CHANGELOG.

Fixes #1579
