• If you've fixed a bug or added code that should be tested, add tests!
• Documentation in docs is updated

Description of changes

pytest’s fixtures can no longer be annotated with marks: https://docs.pytest.org/en/stable/deprecations.html#applying-a-mark-to-a-fixture-function

this was used in tests/tools/_distances/test_distances.py in an attempt to clarify the dependency of some fixtures on the distance test parameter

I switched this to the fixtures simply using the parameter directly.
