[FR]: Enable insert mode by default with vim key bindings

[Leo310]

Feature Description

When Vim keybindings are enabled, the task creation modal defaults to vims Normal mode.
This creates friction in the workflow, as it requires an extra keystroke to begin typing.
I propose that the new TaskNote modal defaults to Insert mode to allow for immediate data entry.

I was pleasantly surprised to see this implemented so quickly in the 4.2.0 release, thanks! However, I noticed that it still defaults to 'normal mode' upon startup.

Thanks @Leo310. Yes, I've noticed that it's not working completely correctly. I've got a proper working fix that I'll include in a release in the next few hours.
