Added mcp 'instructions' attribute to the server

[DanieleMorotti]

Added the instructions attribute to the MCP servers to solve #704 .

Let me know if you want to add an example to the documentation.

why use getattr? I see initialize() returns types.InitializeResult, which has instructions: str | None = None

In fact, we should probably just set self.server_initialize_result. That way devs can read other info too, e.g. protocol version or capabilities

[DanieleMorotti]

As you prefer, the issue was about instructions so I read that value, but now I set the variable as you suggested.
