Switch to regular pytorch channel and restore Python 3.10 for Macs. (#301)

* Switch to regular pytorch channel and restore Python 3.10 for Macs.

Although pytorch-nightly should in theory be faster, it is currently
causing increased memory usage and slower iterations:

https://github.com/lstein/stable-diffusion/pull/283#issuecomment-1234784885

This changes the environment-mac.yaml file back to the regular pytorch
channel and moves the `transformers` dep into pip for now (since it
cannot be satisfied until tokenizers>=0.11 is built for Python 3.10).

* Specify versions for Pip packages as well.

 use ARM packages, and use `nomkl` as described above.
