Issue: Support mouse wheelScrollSensitivity in notebooks
Labels: feature-request,notebook

Type: <b>Bug</b>

As of #117803, we are supposed to set the `workbench.list.mouseWheelScrollSensitivity` property to adjust the scrolling speed for Jupyter notebooks.

The problem here is that Jupyter notebooks are not the only thing using this property: it is also used in the Explorer and various other trees and widgets throughout the UI. This would not be a problem except that the Jupyter notebook plugin seems to interpret the value of this setting as much "slower" than the other widgets. For whatever reason, I need to set `workbench.list.mouseWheelScrollSensitivity = 2` to get Jupyter notebooks to scroll at a reasonable amount on my system. However, doing so makes scrolling in the file tree in the Explorer so fast that it's totally unusable.

I am not sure why this is. As some background, FWIW, for whatever reason, on my system (M1 macOS Sonoma) I needed to set all of the scroll wheel sensitivities lower than 1 to get things to look normal in VSCode. So I have the editor and workbench sensitivity set to around 0.3-0.5. This makes everything else scroll nicely, but causes Jupyter notebooks to scroll extremely slowly. Increase `workbench.list.mouseWheelScrollSensitivity` it throws a bunch of other stuff off.

Jupyter is almost unusable like this and it really needs its own mouseWheelScrollSensitivity property. Is there any workaround at all?
