Implement keybindable "scrollLineUp" and "scrollLineDown" (like in VSCode)

Use case or problem

I’m missing a way to scroll the current view up and down with a keybinding.

It’s a feature I’ve used extensively for many years, most recently frequent in VSCode.
It’s so useful to be able to scroll the current view without having to move the cursor to do so, for example.

Proposed solution

In VSCode, I’ve bound the “scrollLineUp” and “scrollLineDown” commands/shortcuts in the keybindings, and it works perfectly.

I’d love to see a similar “Scroll Line Up” and “Scroll Line Down” entries in Obsidian’s keybindings.

Current workaround (optional)

Lose the context by either having to scroll with a device or moving the cursor.
