The JupyterExtensionIntegration.install() is invoking the incorrect installer from the Jupyter extension #16615
Description
Steps to reproduce
- Open a workspace with a poetry environment
- Make sure the ipykernel package is not installed
- Open a jupyter notebook
- On prompt to install
ipykernelselect yes
Expected
poetry add --dev is invoked
Actual
It invokes pip install -U instead of poetry add --dev
This applies to main/latest
I also noticed there is no unit/integration test for JupyterExtensionIntegration
