Support key repeating in VSCode vim mode

nrb

Add the following in to a script, from https://github.com/VSCodeVim/Vim ```bash $ defaults write com.microsoft.VSCode ApplePressAndHoldEnabled -bool false # For VS Code $ defaults write com.microsoft.VSCodeInsiders ApplePressAndHoldEnabled -bool false # For VS Code Insider $ defaults delete -g ApplePressAndHoldEnabled # If necessary, reset global default ```

nrb

Switched to nvim, no need to do this.
