Bug Report

I can't seem to find a minimal reproducer, but whenever using watchfiles.awatch(), mypy produces the error:
error: "Coroutine[Any, Any, AsyncGenerator[set[tuple[Change, str]], None]]" has no attribute "__aiter__" (not async iterable) [attr-defined]

As can be seen in the aiohttp-devtools repo:
https://github.com/aio-libs/aiohttp-devtools/actions/runs/5328161994/jobs/9652470528?pr=572

To Reproduce

from watchfiles import awatch

async def main() -> None:
    async for i in awatch("/foo"):
        print(i)

Expected Behavior

No error, as in mypy<1.4.
Not sure what exactly triggers the error, as writing another async iterator function myself does not trigger it.
