feat!: replace Jupyter Lab with VS Code notebook support

[JWuzyk]

Improves the experience of using notebooks in VSCode by performing the required setup tasks by default:

• Including the ms-toolsai.jupyter extension.
• Including the ipykernel package as a dev dependency.

Hi @JWuzyk, thanks for this PR! I agree we can improve the experience here. In its current state, isn't this PR more or less equivalent with enabling the with_jupyter_lab option?

I would prefer to integrate this in the existing Jupyter feature, or replace the existing Jupyter feature entirely, or remove the existing Jupyter feature entirely.

The replacement option could look something like this:

• change the with_jupyter_lab feature to with_jupyter
• replace jupyterlab with ipykernel
• possibly have this new feature enabled by default

The removal option would mean that we keep this PR's changes and remove all with_jupyter_lab blocks.

@JWuzyk could you also apply this trick/workaround to automatically select the right kernel in the "settings" section in devcontainer.json:

"jupyter.kernels.excludePythonEnvironments": ["/usr/local/bin/python"]

We should probably log this as an issue to improve once the Jupyter extension allows you to configure a default kernel explicitly.

Added to the PR:

• Enabled format on save for notebooks by default.
• Removed with_jupyter_lab option
• Added work around to automatically select correct kernel

Looks like a nice improvement to me! Do you want to check with anybody else before we merge this?

The only thing I would add is that these changes are VS Code-centric, people using other IDEs or the CLI will have to install JupyterLab themselves. But I think that's OK so all good for me 🙂

Merged! And renamed as the scope changed slightly.
