bin/setup script fails

[gustavosobral]

Describe the bug Running script/setup fails because of caskroom/cask.

To Reproduce Steps to reproduce the behavior:

1. Run script/setup
2. See the following error:

==> Tapping github/homebrew-bootstrap
==> Installing Homebrew dependencies...
/usr/local/bin/docker
Error: caskroom/cask was moved. Tap homebrew/cask-cask instead.
Tapping caskroom/cask has failed!
Using github/bootstrap
Using ngrok
Using tmux
Using overmind
Using nginx
Using postgresql@10
Using terminal-notifier
Using yarn
Homebrew Bundle failed! 1 Brewfile dependency failed to install.

Expected behavior Succeed setting up the project

Additional context Homebrew Cask is now integrated into Homebrew itself and tapping caskroom/cask is not necessary https://github.com/Homebrew/homebrew-cask/issues/14384
