Subject: [PATCH] Do not use warns(None) to check for no warnings

warns(None) is an anti-pattern, and is explicitly forbidden starting
from pytest 8.0. Instead, we catch all warnings, and filter them to be
errors, so they will raise an (uncaught) exception. Drive-by importing
warns from pytest rather than the internal name.
