Jupyterlab requirement

Hi all,

This seems to be related to the PR https://github.com/plotly/plotly.py/pull/5104

The check for jupyterlab is still failing on my end. I have a LabEnv that uses other kernels in other environments. It keeps prod environments lean.

Similar to the original poster of the issue linked to the above PR, I get the following error when trying to plot using plotly.

AttributeError: 'NoneType' object has no attribute 'version'

plotly version:

import plotly
plotly.__version__
'6.0.1'

Python version:

from platform import python_version
python_version()
'3.12.10'

Jupyterlab/host version:

jupyter lab --version 
4.4.1

Jupyterlab/client version:

import jupyter_client
jupyter_client.__version__
'8.6.3'

BTW, the check above for the jupyter_client is probably what needs to be added in the code to fix remote execution. Below is how I 'fixed' it so I can move on for the time being, but probably missing other nuances.

    elif "jupyter-lab" in parent_process:
        jupyter_lab = optional_imports.get_module("jupyterlab") or optional_imports.get_module("jupyter_client")
        if jupyter_lab.__version__ < "3":

Bắt đầu trong plotly/io/_renderers.py tại display_jupyter_version_warnings(), sau đó kiểm tra hành vi của optional_imports đối với jupyterlab và jupyter_client. Tái hiện môi trường JupyterLab và kernel riêng biệt được mô tả trong issue, đồng thời xác minh rằng việc vẽ biểu đồ không còn gây ra NoneType AttributeError, trong khi cảnh báo phiên bản JupyterLab vẫn chính xác.
