Add WAzion to official integrations list

[wazionapps]

Adds WAzion to the official integrations section of the third-party MCP servers list.

WAzion MCP Server exposes 244 WhatsApp Business tools via MCP, supporting both Streamable HTTP and stdio transports.

Repository: https://github.com/wazionapps/mcp-server
npm: wazion-mcp-server
Transport: Streamable HTTP + stdio
License: MIT

One-liner setup:

claude mcp add --transport http wazion https://www.wazion.com/api/mcp/ --header "Authorization: Bearer YOUR_API_KEY"

Note: We are also planning to publish to the MCP Registry via mcp-publisher. We submitted this PR because WAzion is an official integration maintained by the WAzion team.

Thanks for contributing to the MCP servers repo!

We've retired the third-party server list from the README in favor of the MCP Registry — see #3950 for context. The Official Integrations and Community Servers sections no longer exist in the README, so this PR no longer has a target.

Going forward, please publish your server to the MCP Registry using the quickstart guide:
https://github.com/modelcontextprotocol/registry/blob/main/docs/modelcontextprotocol-io/quickstart.mdx

That's where server discovery now happens. Thanks for building on MCP!
