Use "conda_build_tool": "mambabuild" as default again for now

Issue

We have an issue with conda-libmamba-solver that breaks builds that have python in their build environment (e.g., cross-compile builds) and use pip: conda/conda-libmamba-solver#393

To me, it makes much sense for us to use conda-mambabuild as the default until that issue is resolved.
