Playwright docs does not mention that it overrides event loop

[kumaraditya303]

A library should not override the default event loop of an application in asyncio as it causes incompatibilities with other libraries, here:

playwright-python/playwright/_impl/_driver.py

Line 34 in 7de9061

asyncio.set_event_loop_policy(asyncio.WindowsProactorEventLoopPolicy())

playwright overrides the event loop on Python 3.7 on windows for convenience for the end user but there is no such mention in docs that it overrides the event loop.

See incompatibility with tornado : #723

See explanation for this: #723 (comment)
