Prevent MacOS from inserting a period after two spaces

When indenting code in my editor, I wold frequently see a period automatically inserted. For ages I thought this was some plugin of VSCode but when I finally decided to figure out how to disable it, I learned it’s a feature of MacOS. Here’s how to disable it:

defaults write NSGlobalDomain NSAutomaticPeriodSubstitutionEnabled -bool false
