Add Mulesoft MCP server to Official Integrations

[stn1slv]

Description

Adds the MuleSoft MCP server to the Official Integrations section of README.md.
The new row links to the @mulesoft/mcp-server package and describes its purpose (“Build, deploy, and manage MuleSoft applications with natural language, directly inside any compatible IDE.”). This brings first-party MuleSoft support into the list of officially endorsed MCP servers.

Server Details

• Server: Documentation (README.md)
• Changes to: Official Integrations table

Motivation and Context

MuleSoft has released an MCP-compatible server (announced 2025-06-03) that empowers AI-native IDEs to generate, run, and deploy Mule applications through natural-language prompts. Listing it under Official Integrations highlights vendor-maintained, production-ready servers and improves discoverability for MCP users.

How Has This Been Tested?

• Connected Cursor IDE to @mulesoft/mcp-server via the catalogued entry.
• Verified scenarios:
  1. Project scaffolding
  2. Local run
  3. CloudHub deployment
  4. Exchange search/list
     All commands executed successfully with OAuth credentials as per the vendor guide.

None. Documentation-only addition.
