I use the jupyter-lab module in main.tf with default parameters. However, when I create a new Notebook, I encounter issues with importing packages installed using pip.

Steps to reproduce:

1. In a Notebook, run !pip install pandas --break-system-packages (using --break-system-packages to bypass the externally-managed-environment error). The package gets installed to ~/.local/lib/python3.12/site-packages.
2. Run import pandas as pd in the Notebook. This raises a ModuleNotFoundError.

Findings:

Output of !which pip in the Notebook: /usr/bin/pip
Output of sys.executable in the Notebook: /home/coder/.local/share/pipx/venvs/jupyterlab/bin/python
It seems that when JupyterLab is installed via pipx, it uses its own Python environment, separate from the system's pip. As a result, packages installed via pip are not accessible to JupyterLab.

Expected behavior:

Packages installed using !pip install in a Jupyter notebook should be available for import without additional configuration.
