SM doesn't autoinstall torch-directml on AMD/Windows for ComfyUI

[brknsoul]

These are the instructions to manually install torch-directml in a StabilityMatrix ComfyUI environment;

Go to StabilityMatrix install folder > Data > Packages > ComfyUI, open cmd here
run:
venv\scripts\activate
pip install torch-directml
deactivate
close cmd
Open SM, click settings Cog, scroll to bottom and add --directml

If this set of instructions could be automated while installing ComfyUI (as they are on SD.Next), that'd be great.
