Brew command is outdated "brew cask install" should be "brew install --cask"

[mhooimeijer]

This is the outdated code brew cask install --appdir="/Applications" docker

Should be using: brew install --cask --appdir="/Applications" docker

I guess this refers to the development environment set up instructions in the v2.2 and/or v2.3 documentation? I suspect that this commands were probably correct at the time of release, and has already been updated to the new syntax in the v2.4 and latest documentation.
