test: skip ibis test on unsupported python version

[dangotbanned]

test_ibis_with_date_32 was always emitting the same warning on 3.8:

================================================================================================= warnings summary =================================================================================================  
tests/vegalite/v5/test_api.py::test_ibis_with_date_32   

/altair/altair/vegalite/v5/api.py:233: UserWarning: data of type <class 'ibis.expr.types.relations.Table'> not recognized
     warnings.warn(f"data of type {type(data)} not recognized", stacklevel=1)  

-- Docs: https://docs.pytest.org/en/stable/how-to/capture-warnings.html 
==================================================================================== 210 passed, 1 xfailed, 1 warning in 17.92s ====================================================================================

@MarcoGorelli wanted to check in with you to see if this is a reasonable skip?

I was a little confused on the ibis.expr.types.relations.Table appearing on a python below their minimum

[MarcoGorelli]

Hi @dangotbanned !

I just tried installing altair from source on Python3.9, and this test runs fine for me without any warnings

Could you show where the warning is appearing please? Is it in a CI run?

@MarcoGorelli just looked through the CI runs and I can't seem to find any warnings.

I think this is win32 only, but for repro if you have access to windows:

>>> hatch test --python 3.8 -k test_ibis_with_date_32

If you can confirm that you get the same on windows, I'll update the skipif to include that as a constraint

[MarcoGorelli]

Sure but that's 3.8?

On 3.8, I can reproduce, even on Linux - the maximum Ibis version installable on Python 3.8 is Ibis 5.1.0, which didn't yet have the dataframe interchange protocol

I think just 3.8 needs skipping?

@MarcoGorelli you're right!

So it looks like just 3.8, and my assumption on sys.platform was unrelated

[MarcoGorelli]

Thanks for updating!

@MarcoGorelli wanted to check in with you to see if this is a reasonable skip?

fwiw, looks good to me!

[jonmmease]

Thanks both!
