make editable refer to root dir with setup.py

[a-sumo]

I'm using an M1 chip and I encountered issue #5 . As suggested, I ran:

git clone https://github.com/dattalab/keypoint-moseq && cd keypoint-moseq

conda env create -f conda_envs/environment.linux_cpu.yml

And encountered the following error:

Pip subprocess error:                                                           
ERROR: file:///Users/armand/Documents/keypoint-moseq/conda_envs (from -r /Users/armand/Documents/keypoint-moseq/conda_envs/condaenv.m8fzb9y8.requirements.txt (line 2)) does not appear to be a Python project: neither 'setup.py' nor 'pyproject.toml' found.

CondaEnvException: Pip failed    

Which turned out to be caused by the line --editable in the environment.linux_cpu.yml not referring to the root directory containing the setup.py file. After making the changes in this commit, I successfully created the conda environment.
I assume this must be true for all 4 environments in conda_envs/ directory so I made the same change in all 4 environment files.

Thanks for the PR! Were you able to import keypoint_moseq and/or jax in the resulting environment? I want to confirm whether this is a good solution for M1 users.

FYI: Here's the related issue for Apple Silicon + Jax: jax-ml/jax#8074

(As of March 2023, it doesn't sound like it works natively yet with Metal.)

Can also confirm that this PR fixes the conda environment installations.
