Subject: [PATCH] :books: Add WebSocket proxy configuration for MCP in Nginx
 example (#10152)

The current Nginx example doesn't include the required Websocket settings to correctly proxy /mcp/ws, and leads to WebSocket connection error when trying to connect in a design. Adding this lines fixed the issue.
