(chore): Have stylelint ignore the build directory.

[Garbee]

This way when viewing the build files in an editor it won't complain about the output style.

💎 LGTM Thank you!

Only thing is could you git commit --amend this to fit our commit message guidelines? e.g.

git commit --amend -m "chore(infrastructure): Have stylelint ignore the build directory"

If you've pulled from master recently you can run npm i again and it'll install the validate-commit-msg hooks for you. Also, you can use commitizen to automate writing these commit messages 😄

Also feel free to add [ci skip] to your commit message since this really doesn't require TravisCI to run.
