Fix weird characters in macOS Monterey Shortcuts

It took me a while to track down what was causing weird character strings such as `^Q` to appear in the Shortcuts app in macOS Monterey, so I documented the "fix" here. The command to run to hide the control characters is : ``` defaults write NSGlobalDomain NSTextShowsControlCharacters -bool false ``` Further documentation can be found here: https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/EventOverview/TextDefaultsBindings/TextDefaultsBindings.html
