Unused awaitable with TaskGroup

[Dreamsorcerer]

import asyncio

async def main() -> None:
    async with asyncio.TaskGroup() as tg:
        tg.create_task(asyncio.sleep(1))

With unused-awaitable enabled, this code generates an unused awaitable error. TaskGroup is expected to wait on any created tasks, so there is no need to await on them.

Perhaps TaskGroup can be special-cased to ignore this error, or maybe special-case Task so the rule only applies when it is returned from asyncio.create_task()?

Just upgraded to mypy 1.5 and Python 3.11.4, and can reproduce this behaviour.
