docs(server): Correct custom endpoint example for streamable HTTP transport

[IAmSurajBobade]

Description

• On website example server code with Streamable HTTP transport uses AddMCPRoutes method to mount Streamable HTTP Server handler, which does not exist.
• Link to document: https://mcp-go.dev/transports/http#custom-endpoints

Fixes #541 (if applicable)

Before:

func main() {
    // Create MCP Server
    s := server.NewMCPServer("Custom StreamableHTTP Server", "1.0.0")
    
    // Create HTTP server with custom routes
    mux := http.NewServeMux()
    
    // Add MCP endpoints
    server.AddMCPRoutes(mux, s, "/mcp")
}

After:

func main() {
    s := server.NewMCPServer("Custom StreamableHTTP Server", "1.0.0")
    
    // Create HTTP server with custom routes
    mux := http.NewServeMux()
    
    // Add MCP endpoints
    mux.Handle("/mcp", server.NewStreamableHTTPServer(s))
}
