fix benchmarks compatibility with newer pytest-cases (rapidsai#14764)

Reverts changes from rapidsai#14756.

* updates `cudf`'s tests to be compatible with the latest `pytest-cases` ([version 3.8.2](https://pypi.org/project/pytest-cases/#history))
* puts a floor of `pytest-cases>=3.8.2` on that project to be sure older versions aren't used
