provision-with-micromamba is deprecated

Using mamba-org/setup-micromamba@v1 instead.

All the tests that use numba and masked arrays are failing. In a way, they were probably wrong before even when they passed b/c numba doesn't support masked arrays. xref.: numba/numba#1834

Ideally we should fix the tests but we can pin to numba<0.57 to restore the old behavior.

@kwilcox I'm not sure pinning to an old numba is the best course of action here. What do you think? I would just fail,for now, when masked array are used with numba, until numba supports them properly.

@srstsavage and @kthyng I'm self-merging this one to move things forward. Note that we have a pin on numba that limits ioos_qc use with Python >=3.11. I'll investigate that but for now we should issue a new release to prevent folks from installing it with an unpinned numba.

PS: I also fixed some tz-aware date comparisons by making all the tests tz-naive. We should add specific tz-aware tests though in the future.

@ocefpaf 👍 thank you!
