Documentation about `aiohttp_unused_port` inaccurate?

[ablakey]

The documentation here: https://docs.aiohttp.org/en/stable/testing.html#aiohttp.test_utils.aiohttp_unused_port

states:

"Changed in version 3.0: The fixture was renamed from unused_port to aiohttp_unused_port"

But I cannot find aiohttp_unused_port anywhere in the 3.5.4.
