Toggle Helix mode

[yilmazer]

I am confused about how to easily assign a key binding to toggle Helix mode. There is no "ToggleHelixMode" action like workspace::ToggleVimMode yet. In the past, I used 'vim': { "default_mode": 'helix_normal' } but this setting doesn't work anymore. You can still find it in the documentation.

There's an action for vim::SwitchToHelixNormalMode, but it only toggles on, not off. Am I missing something here?

#41454 enabled helix mode toggle. It may also be helpful to update the documentation. Thanks!
