Sorry; actually, does that change anything? I mean, either way we need a function scope fixture, and my understanding is that it will undo the changes just the same.

Replace the use of private
monkeypatchAPI with the standard invocations to fix compatibility with pytest 9.1, as well as to make the tests more reliable in the future.The previous code operated on
monkeypatchfixture internals to trigger clearing environment variables expected by tests at the beginning of tests, and reverting any changes made by the tests. However, this does not seem strictly valid, and it actually lead to tests making wrong assumptions. For example,test_disable_dotenv_from_envrelied on a previous test unsettingFOOin the environment, and failed ifFOOwas set while it was run alone.The new logic uses public API only: it cleans up the standard set of environment variables for every test, and additionally cleans up variables specifically used by dotenv tests. With this approach, it is entirely possible for a test to leave the environment "dirty"; however, that's fine since other tests need to clean up the environment anyway to account for user-set environment variables.
Fixes #6071
