    GH-50277: [CI][Python] Avoid using generators for test parametrization on newer Pytest (#50278)
    
    ### Rationale for this change
    
    On the hypothesis tests we treat Warnings as errors and the job has been failing with the latest Pytest version (9.1.0). This is related to:
    - https://github.com/pytest-dev/pytest/issues/13409
    
    With the latest pytest using generators for parametrization has been deprecated.
    
    ### What changes are included in this PR?
    
    Change the generator that was causing the failures and return a list of supported_factories instead.
    
    ### Are these changes tested?
    
    Yes both locally and the archery test that was failing.
    
    ### Are there any user-facing changes?
    
    No
