updates setup-conda on ci to use miniforge instead of miniconda, which avoids getting anything from the defaults (Anaconda) channel. Also switches the installer to mamba>=2.6, which enables sharded repo data (less downloads, should be faster solves).
I'm not sure what's going on in #4191, but it's always a good idea to make sure channels aren't mixed before diving too deep into debugging conda installs.
closes #4191 if it works
