JupyterLab 4 support

[JasonWeill]

JupyterLab 4.0.0 was released earlier today, May 15, 2023. Support JupyterLab 4 with Jupyter AI.

FYI,

I failed to use Jupyter-ai in Jupyterlab 4. I once succeeded in Jupyterlab 3.6.

The cell

%%ai chatgpt -f math
Generate the 2D heat equation.

caused an error:

AuthenticationError                       Traceback (most recent call last)
Cell In[16], line 1
----> 1 get_ipython().run_cell_magic('ai', 'chatgpt -f math', 'Generate the 2D heat equation.\n')
....

File ~\anaconda3\envs\jupyterlab4\lib\site-packages\openai\api_requestor.py:687, in APIRequestor._interpret_response_line(self, rbody, rcode, rheaders, stream)
    685 stream_error = stream and "error" in resp.data
    686 if stream_error or not 200 <= rcode < 300:
--> 687     raise self.handle_error_response(
    688         rbody, rcode, resp.data, rheaders, stream_error=stream_error
    689     )
    690 return resp

AuthenticationError: <empty message>

I'm using Jupyter Lab 4.0.2. Cell magic works, but chat button does not appear. It was visible before updating Jupyter Lab. In the pip update of Lab was:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
jupyter-ai 0.7.3 requires jupyterlab<4,>=3.5, but you have jupyterlab 4.0.2 which is incompatible.

Edit: Now is working, after trying to reinstall extensions and running with more privileges
Edit 2: It still does not work, apparently a 3.x version of Lab is still installed and was running it by mistake. Running 4.0.2 chat button is not visible in the side bar.

Possibly relevant Discourse thread about targeting both versions: https://discourse.jupyter.org/t/jlab-extensions-that-target-both-jlab3-and-jlab4/20100

The means of inserting a cell with prepopulated content seems to have changed in Lab 4; see jupyterlab/jupyterlab#14730
