Use conda-build instead of conda-mambabuild (#723)

This changes from `conda mambabuild` to `conda build`. Conda now uses the mamba solver so no performance regressions are expected.

This is a temporary change as we plan to migrate to `rattler-build` in the near future. However, this is needed sooner to drop `boa` and unblock Python 3.13 migrations.
