Reproducible example

[project]

channels = ["conda-forge"]

[dependencies]
python = "3.11.9"

[pypi-dependencies]
tqdm = "*"
python_dotenv = "*"

Issue description

When running pixi install -vv:

 INFO pixi::environment: verifying prefix location is unchanged, with prefix file: /home/pan/.pixi/envs/default/conda-meta/pixi_env_prefix
 INFO pixi::lock_file::update: the lock-file is up-to-date

✔ The default environment has been installed.

We see that 'python-dotenv' is used.

But when doing pixi list | grep dotenv:

❯ pixi list | grep dotenv
python_dotenv     1.0.1                         53 KiB     pypi   python_dotenv-1.0.1-py3-none-any.http.whl

'python_dotenv' is used.

This makes if hard to search for packages in your pixi.toml based on the information provided during the installation when troubleshooting dependency issues, for instance.

Expected behavior

Pixi should stick to one convention.
