deps: remove unneeded @types/colors package (#319)

- it had a deprecation warning on install stating that types were
  built-in now
  - confirmed that my editor picks up the types fine without and that
    builds still work

- auto-alphabetize deps
- update package-lock.json version to match package.json version
  - NPM did both of these automatically when I ran `npm install`
