• Spoiler: they aren't.
• Fixes Add a RuboCop rule for sorting EnvConfig keys #17027.
• As part of Volunteer Month at work I introduced @hharen to contributing to Homebrew, cd $(brew --repo), brew tests, brew style, etc.
• We also started to write a RuboCop for this. But my current thinking is that this test might be sufficient since it might be easier to notice "oops, a test is failing and I've added a new envvar" and re-alphabetize it than to write a RuboCop linter for it to do the one-time autofix. Considering how little this gets changed?

Yup, I agree, great work here @issyl0 and @hharen (and nice to "see" you again @hharen)!

Indeed, I totally didn't know that homebrew is written in Ruby! ❤️❤️❤️
