Fix Pytest's deprecation warnings about nose usage (#8758)

Pytest 7.2.0 deprecated plain `setup` and `teardown` functions and
methods as nose idioms:
https://docs.pytest.org/en/latest/changelog.html#pytest-7-2-0-2022-10-23

`setup` can be safely replaced with `setup_method`:
https://docs.pytest.org/en/stable/deprecations.html#setup-teardown

Fixes: https://github.com/encode/django-rest-framework/issues/8757
