Added Ethics MCP server to Readme

[r-huijts]

Description

This PR adds the Ethics MCP Server to the Community Servers list in README.md, providing a link and succinct overview of its bias-detection, fairness-validation, and compliance-audit capabilities.

Server Details

• Server: GitHub
• Changes to: README.md

Motivation and Context

As more teams adopt MCP, they need integrated governance tooling. Ethics MCP Server fills that gap by enabling LLM clients to self-audit for bias, fairness, and policy compliance before delivering outputs.

How Has This Been Tested?

• Previewed in GitHub’s Markdown renderer to confirm formatting, link correctness, and alphabetical placement.
• Clicked the new link to verify it points to r-huijts/ethics-mcp-server.
• Ran a sample ethics check via an LLM client against the server to ensure the bias/fairness modules initialize correctly.

Breaking Changes

None.

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation update
