Add an explanation for implementing MCP server hosting using Higress

[johnlanni]

Description

Adds Higress MCP Server Hosting to Additional resources. It is a solution that allows running MCP servers on API Gateway(based on Envoy)

Motivation and Context

MCP makes APIs more AI-friendly, and the management of MCP servers shares many similarities with traditional APIs, such as invocation observation of tools calls, rate limiting, authentication, and authorization. Higress offers a way to develop WASM plugins, extending the capabilities of MCP servers on the API gateway. This approach simplifies the hosting of MCP servers and allows for the reuse of governance capabilities that have been established in the era of traditional APIs.

How Has This Been Tested?

Internal testing has been completed. About to be widely promoted and used on Alibaba Cloud
