Fix mcp new --transport flag documentation

Remove incorrect --transport=http option which is not supported.
The mcp new command only supports stdio and sse transports.

Updated scaffolding examples to use correct transport options
and fixed streamable HTTP example to use SSE transport instead.

 The scaffolding creates a complete project structure with:
 
-- Server setup with chosen transport (stdio, SSE, or streamable HTTP)
+- Server setup with chosen transport (stdio or SSE)
 - TypeScript configuration with modern ES modules

 - Automatic wiring of imports and initialization

 Create and run a local streamable HTTP server:
 
 ```bash
-# Create a new MCP server with streamable HTTP transport
-mkdir my-http-server && cd my-http-server
-mcp new tool:example_tool --transport=http
+# Create a new MCP server with SSE transport (streamable HTTP not available in scaffolding)

 # Install dependencies and build
 npm install && npm run build
 
-# Start the server (will run on http://localhost:3000)
+# Start the server (will run SSE transport)
 npm start

 In a separate terminal, connect to your local server:
 
 ```bash
-# Connect to local streamable HTTP server
-mcp tools http://localhost:3000
+# Connect to local SSE server (adjust URL based on your server's SSE endpoint)
+mcp tools http://localhost:3000/sse

-mcp call example_tool --params '{"input": "test"}' http://localhost:3000

 # Use with different output formats
-mcp tools --format pretty http://localhost:3000
