Remove -q flag from mamba install, add mamba list for default install.

Add mamba list calls.
Try the conda experimental sovler solution.
Use an explicit install command with all packages, --freeze-installed did not seem to work.
Try removing lapack before installing scipy.
Make sure only the conda forge channel is used in scipy install.
Use SciPy 1.9 with Ipopt 3.12.
Try skipping only the builds that have issues with scipy being involved.
