[Documentation] VS Code External Editor

[JulianWebb]

Hello,

I'm so excited that this Add-on exists, I find scripting to be easier to wrap my head around than drag and drop nodes.

In the information given on the Blender Add-on screen, it doesn't specify that a Python Extension needs to be installed for this to work. Having come from writing mostly Javascript, this took me a bit off guard at first but I figured it out.

In the documentation, it only specifies that the main Python Extension is required, however the setting that needs to be changed is added by the Pylance Extension. The latter is normally installed by the former, but it doesn't always, such as in cases of network issues, using VS Codium, or other possible scenarios.

I would recommend adding even a small snippet about this in the Documentation, and, if possible, point the user to that via the Add-on Preferences section rather than have differing versions of the same instructions in multiple places.

Cheers.
