Bind j and k to scrolling

[panglesd]

Requires #14 to be done first.

Keyboard arrows are common to scroll, but so are j and k on TUIs. The goal of this task is to add the following bindings:

• j to scroll down,
• k to scroll up.

Keybindings can be either added in interactive_viewer.ml alongside the other key bindings, or in the keybindings defined in the vscroll_area function, in nottui_widgets.ml

Hi @panglesd , @Julow ,
I would like to work on this issue. Once #14 is done can you Please assign me this?

Unfortunately it depends on another issue being closed, which is not the case yet!
However, we are lacking good medium issues right now... We'll be adding more today!

In the meantime, let's assign this to you! We might unassign you if we have a better task to assign you to.

@panglesd , Thank you for the update! If any other tasks become available or are better suited for me, I'm flexible and open to being reassigned accordingly. Looking forward to contributing further to the project!
