Skips polars DB test on 3.12

[skrawcz]

Why? It complains about connectorx not being installed. But it is! and this only happens on python 3.12. Since python 3.12 is so new, likely something has changed in polars or connectorx. So skipping test for now on 3.12.

Changes

• polars extension test

How I tested this

• locally
