[Bug]: poetry self add <plugin> fails in devbox

[justinTM]

Current Behavior (bug)
I'm getting a ton of Nix errors when trying to add a poetry plugin inside a devbox shell:

justins-MacBook-Pro:trzpyutils justin$ which python
justins-MacBook-Pro:trzpyutils justin$ which poetry
justins-MacBook-Pro:trzpyutils justin$ devbox shell
Info: New devbox available: 0.8.4 -> v0.8.5. Please run `devbox version update`.
Starting a devbox shell...
You can activate the virtual environment by running 'source $VENV_DIR/bin/activate'
Using virtualenv: /Users/justin/git/gl/****/trzpyutils/.venv

```

**Expected Behavior (fix)** A clear and concise description of what you expected to happen. I guess I expected poetry plugin to install using the devbox poetry binary, and the virtual environment activated by devbox thru poetry...

Additional context
Please include the output of devbox version -v and
a copy of your devbox.json file.

[gcurtis]

I can reproduce this. Still investigating, but it looks like PYTHONPATH is still set to the Nix store after activating the virtual environment, so poetry is trying to install dependencies there.

$ devbox shell
(devbox) $ . $VENV_DIR/bin/activate
(.venv) (devbox) $ poetry self add "poetry-dynamic-versioning"
Using version ^1.2.0 for poetry-dynamic-versioning

Oh, I just noticed that this is a plugin being added to poetry's own environment, not the virtual environment. I'm trying to use devbox add python311Packages.poetry-dynamic-versioning instead, but poetry doesn't seem to pick it up.

[gcurtis]

@justinTM I looked into this for a bit, but unfortunately I don't think there's an easy way to add poetry plugins right now. I even tried to get poetry-dynamic-versioning working directly from a Nix flake, but couldn't get it to show up in poetry self show plugins. This issue has some more details on poetry plugins + Nix.

We'll have to look into prioritizing some work + debugging time to get this working smoothly.
