Testing: The module is a provisional

[ppena-LiveData]

https://docs.aiohttp.org/en/stable/testing.html says, "The module is a provisional," but there are many different modules (and packages) discussed on that page, so it's not clear what is provisional. Does someone know what exactly is provisional?

Well, it refers to aiohttp.test_tools. That module is no longer named that, and the note was added 7 years ago. So, I think we can probably just remove that notice today.
