Use of deprecated asyncio.iscoroutinefunction

[ZeroIntensity]

asyncio.iscoroutinefunction is the same as inspect.iscoroutinefunction (since it's conception, I think), and is deprecated on 3.14 (IIRC, the plan is to remove it in 3.16).

It's used in a few places, such as here

pytest-asyncio/pytest_asyncio/plugin.py

Line 179 in cf10674

return asyncio.iscoroutinefunction(obj) or inspect.isasyncgenfunction(obj)

I have a PR ready to switch things over to inspect.iscoroutinefunction -- since they're exactly the same, this won't break anything (and saves you guys a headache a few years down the line 😄)

I wasn't aware of the deprecation, but it absolutely makes sense.

Thanks @ZeroIntensity!
