[Feat] [pydeck] Update for JupyterLab 3

Target Use Case

First, there is an issue with the jupyter-widget module in JupyterLab 3 (#5615).

Second, using a prebuilt extension in JupyterLab 3 would allow a more standard installation for pydeck. A user could just run pip install pydeck to install the JupyterLab extension and not require a rebuild.

Proposal

I think I was able to make the update for JupyterLab 3 here by following the advice in the ipywidgets CHANGELOG:

https://github.com/dakoop/deck.gl/tree/pydeck-8.7

Then, I tried to create a prebuilt extension. Since jupyter-builder uses webpack 5, and pydeck uses 4, there were some headaches, including something that seems to be related to the acorn package. pydeck specifies a resolution for acorn to 7.4.1, and jupyter labextension build just hangs. If I remove the resolution (which I think allows acorn versions to be different for different packages), the build suceeds. This should allow a python -m build in the bindings/pydeck directory, which produces a wheel that can be used for pip. That branch is available here:

https://github.com/dakoop/deck.gl/tree/pydeck-8.7-prebuilt

Start in the bindings/pydeck directory and compare the referenced pydeck-8.7 and pydeck-8.7-prebuilt branches. Run jupyter labextension build and python -m build to investigate the acorn resolution issue. Done means a JupyterLab 3 prebuilt extension is packaged in the wheel and can be installed with pip.
