Visualizations fixes follow-up (#9252)

Addressing review suggestions from #9130

- Removing `N` binding
- Removing duplicated `Toggle fullscreen vis` binding

A few important differences from the suggested implementation:
1. There is no easy way to implement `nextType` on GraphEditor – we simply don’t have the required API
2. The keydown handler in `GraphVisualization` must be defined on window level still, otherwise it won’t get keydown events unless visualization is focused, and thus `nextType` won’t work because of (1)

No visual changes to the IDE.
