Fix conda builds defaulting to python 3.12 (#315)

* See if updating to setup-miniconda v3 fixes Windows build

* Use python 3.10 instead of 3.9 on Windows

* Explicitly install correct python version for linux & macos conda

* Fix version number should be a string

* Maybe the problem with adding conda to path for macos is lack of quotes?

* Add more echo statements for debugging macos

* Add more echo statements for debugging macos (try again)

* Install conda on macos since it is no longer included in image

* conda activate instead of mamba activate

* Run conda init before conda activate

* Have to restart shell after conda init

* Specify bash options to correctly activate on macos
