Async example typo

[vtermanis]

Hi Vital team,

Nice SDK!

I think I spotted a small typo in your async example:

from vital.client import AsyncVital

import asyncio

vital_client = AsyncVital(
  api_key="YOUR_API_KEY",
)

async def get_lab_test() -> None:
    lab_test = vital_client.lab_tests.get('order-id')
    print(lab_test)

asyncio.run(get_lab_test())

I believe there's an await missing from the lab_test assignment line.
