Add command for minimal fixing ESLint issues.

This enables quick testing. E.g., remove a rule from `.eslintrc-minimal` then run `npm run lint-minimal` to check how many errors there are, then run `npm run fix-minimal` to see how many errors can be fixed. Either fix the rest and be happy or revert everything and go on with your life 😇
