conda installation

[abearab]

It would be great if you can enable conda installation.

User story

(Deprecated) Installing extensions with the jupyter labextension install command is now deprecated and will be removed in a future major version of JupyterLab.

Users should manage prebuilt extensions with package managers like pip and conda, and extension authors are encouraged to distribute their extensions as prebuilt packages 

Additional context

Also, I had to install nodejs through conda, you might want to add that as a dependency conda install conda-forge::nodejs

/home/abea/miniconda3/envs/jupyter/lib/python3.12/site-packages/jupyterlab/debuglog.py:55: UserWarning: ValueError: Please install Node.js and npm before continuing installation. You may be able to install Node.js from your package manager, from conda, or directly from the Node.js website (https://nodejs.org).
