Describe the bug
When session.get_prompt(prompt.name) is called the GetPromptResult doesn't return the prompt description

To Reproduce
Steps to reproduce the behavior:

  1. Create a FastMCP server and add a prompt description
@mcp.prompt(description="This prompt summarizes the brave search data")
def summarize_brave_data() -> str:
   return f"ABCABCABCB"
  1. Create a client and call list_prompts along with get_prompts
prompt_data = await self.session.get_prompt(prompt.name)
print(prompt_data)
  1. Output:-
INFO     Processing request of type GetPromptRequest                                                     server.py:534
meta=None description=None messages=[PromptMessage(role='user', content=TextContent(type='text', text='ABCABCABCB', annotations=None))]

Expected behavior

INFO     Processing request of type GetPromptRequest                                                     server.py:534
meta=None description="This prompt summarizes the brave search data" messages=[PromptMessage(role='user', content=TextContent(type='text', text='ABCABCABCB', annotations=None))]
