Missing MCP Tools example for streamable-http transport

[jackwotherspoon]

The docs for MCP Tools are lacking significantly.

They do not showcase how to create toolsets for the sse or streamable-http transports, only stdio.

There should be an example added for streamable http at the very least as this is the recommended transport for remote MCP servers to use.

GitHub remote MCP usage example:

import os
from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool import MCPToolset, StreamableHTTPConnectionParams

root_agent = LlmAgent(
    model="gemini-2.5-pro-preview-06-05",
    name="github_agent",
    instruction="You are a helpful assistant that can answer questions about GitHub.",
    tools=[
        MCPToolset(
            connection_params=StreamableHTTPConnectionParams(
                url="https://api.githubcopilot.com/mcp/",
                headers={
                    "Authorization": "Bearer " + os.getenv("GITHUB_PERSONAL_ACCESS_TOKEN"),
                }
            )
        )
    ],
)

Docs also need to be updated to use the new connection param classes and not server params....
