Enable Key Repeat in Github Codespaces in OS X

When navigating in vim-mode I sometimes hold the j or k keys to move up or down. I know, there are more efficient ways to get around, but oh well, it's what I find myself doing.

Out of the box on OSX holding a key triggers a special Press and Hold Mode that is used to easily input accent marks rather than repeat the keys. To change this, you can execute:

defaults write NSGlobalDomain ApplePressAndHoldEnabled -bool false
