pythonPackages.scikitlearn: apply `max_iter` patch from scikitlearn master (#43483)

See https://github.com/scikit-learn/scikit-learn/pull/10723

This fixes the build of `scikitlearn` on master and nixos-unstable.

The issue is originally an upstream issue
(see https://github.com/scikit-learn/scikit-learn/issues/10619) which
was fixed on master and was mainly caused by changes to the environment.

Closes #43466
