Ctrl-j/-k to select cell in jupyter command mode as well?

[tqfjo]

I think it might make sense to have those bound by default in jupyter command mode too for simplicity.

(Maybe I'm alone on this, but I still very frequently press those keys in juptyer command mode despite trying to learn to double-check which mode I'm in beforehand.)

For reference, this how you map them:

        // default is editMode only
        {
            "selector": '.jp-Notebook.jp-mod-insertMode',
            "keys": [
                'Ctrl J'
            ],
            "command": 'notebook:move-cursor-down'
        },
        
        {
            "selector": '.jp-Notebook.jp-mod-insertMode',
            "keys": [
                'Ctrl K'
            ],
            "command": 'notebook:move-cursor-up'
        },
