CI: Fix import of coo_matrix after scipy dev upgrade
New scipy_dev renamed ``coo`` to ``_coo`` to make it private
Fixes the scipy affected tests. The numpy affected tests are still failing Best guess is this np.quantile PR https://github.com/numpy/numpy/pull/18203 is causing the current build failures. I think it is https://github.com/numpy/numpy/commit/cd7a02a4db7e760b881f3feeb832ffd84fa8645a @phofl duplicate of #44362? The scipy part yes
