Fix conda environment not setting up correctly in Linux

[WorldTeacher]

I tried installing this fork on Linux (Arch if that matters), but encountered this error while installing:

CondaEnvException: Pip failed

To fix this, I removed the -e git... part in the .yaml file and added it to the readme.md, where I added the instructions you provide in progrockdiffusion. This can probably be done in the .yaml file, but I have no knowledge in that area, so I opted for this way.

It'd probably be better to rename the "for Linux" part I added to the readme to "Windows/Linux" since it also affects the windows installation if the yaml gets changed.

Hi - going to see if I can replicate this, because a number of people have installed this on linux and macOS without issue, and I would prefer to keep the install handled by the yaml file if possible. So, I'm holding off on merging this until I can verify it as well as explore a solution that doesn't require additional install commands.

[WorldTeacher]

Thanks for letting me know ^^ Finding a way that doesn't require more install commands would be better. Let me know if I can do anything to help.

I had installed this on Linux (Arch) without any addition steps or problems. Maybe there was some intermittent problems with GitHub.
