Fix CI errors in statspace test suite (pymc-devs#251)

* Ignore numpy depreciation warnings from statsmodel

* Squeeze result vector-matrix multiplication with (1, 1) matrix to avoid shape error in numpy 1.25.2

* Consolidate all project settings into `pyproject.toml`

* Delete unused`pytest.ini` and `setup.cfg`

* Remove unnecessary filtered warnings

* Change pathfinder jax import from deprecated pymc.sampling_jax to pymc.sampling.jax

* Skip pathfinder test if python < 3.10

* Add some comments to `pyproject.toml` to explain what warnings are being ignored and why
